    To examine whether a program to increase the wearing of seat belts in a South African urban area would be worthwhile in societal terms. A cost benefit analysis of a one year enhanced seat belt enforcement program in eThekwini (Durban) Municipality. Data were drawn from two main sources--a 1998 study of the cost of road crashes in South Africa and, given the absence of other data, a meta-analysis of the effectiveness of various types of interventions to reduce road crash casualties in the United States--and were analyzed using cost benefit analysis. A program designed to enforce greater wearing of seat belts, estimated to cost 2 million rand in one year, could be reasonably expected to increase seat belt usage rates by 16 percentage points and reduce fatalities and injuries by 9.5%. This would result in saved social costs of 13.6 million rand in the following year or a net present value of 11.6 million rand. There would also be favorable consequences for municipal finances. Investment in a program to increase seat belt wearing rates is highly profitable in societal terms.

    Analytical and petrological software developments over the past decade have seen rapid innovation in high-spatial resolution petrological techniques, for example, laser-ablation ICP-MS, secondary ion microprobe (SIMS, nano-SIMS), thermodynamic modelling and electron microprobe microscale mapping techniques (e.g. XMapTools). This presentation will focus on the application of petrochronology to ca. 3.55 to 3.33 billion-year-old metavolcanic and sedimentary rocks of the Onverwacht Group, shedding light on the earliest geologic evolution of the Paleoarchean Barberton greenstone belt (BGB) of South Africa. The field, scientific drilling and petrological research conducted over the past 8 years, aims to illustrate how: (a) LA-ICP-MS and SIMS U-Pb detrital zircon geochronology has helped identify the earliest tectono-sedimentary basin and sediment sources in the BGB, as well as reconstructing geodynamic processes as early as ca. 3.432 billion-years ago; (b) in-situ SIMS multiple sulphur isotope analysis of sulphides across various early Archean rock units help to reconstruct atmospheric, surface and subsurface environments on early Archean Earth and (c) the earliest candidate textural traces for subsurface microbial life can be investigated by in-situ LA-ICP-MS U-Pb dating of titanite, micro-XANES Fe-speciation analysis and metamorphic microscale mapping. Collectively, petrochronology combined with high-resolution field mapping studies, is a powerful multi-disciplinary approach towards deciphering petrogenetic and geodynamic processes preserved in the Paleoarchean Barberton greenstone belt of South Africa, with implications for early Archean Earth evolution.

    The Barberton Greenstone Belt (BGB, South Africa) is one of the few Archean remnants where the tectonic evolution of the Early Earth can be studied. The first formation of the crust is a controversially discussed topic among geoscientists. Tectonics on the Early Earth might have been similar to the plate movement and their driving forces that we observe today. However, regarding that some fundamental conditions like the thermal setting were considerably different at this time other processes like vertical mass transport might have played the governing role in tectonics. Therefore contrasting evolutionary models of the BGB exist, mainly based on a number of geological and petrological studies. However, there is only little information on its deeper architecture. For a better understanding of past processes and the character of the tectonic regime which led to the formation of the BGB, magnetotelluric (MT) surveys were carried out as a part of the German-South African Inkaba yeAfrica research initiative. At approximately 200 MT sites aligned along six profiles (approx. 80 to 110 km length) data was collected during two field experiments in 2009 and 2010. The MT method images the electrical conductivity of rocks and is particularly sensitive to imprints of tectonic processes resulting in persistent mineralization e.g. along shear planes. Against the surrounding of significantly conductive geological units like the Phanerozoic Transvaal cover, the rocks of the BGB are generally characterized by high electrical resistivities. Particularly plutons such as the Dalmein Pluton can be traced deeply into the crust. Contrary, faults of the BGB appear as zones of high conductivity down to a depth of 5 to 10 km. We will present 3D inversion results indicating an extension of the plutons of the western BGB beneath the Transvaal cover and a sharp conductivity contrast of the BGB compared to the eastern batholiths. We will discuss existing models of the evolution of the BGB in view

    We investigated the data obtained from a geophysical survey of the Greenstone Belt in the Barberton mountain land in the Transvaal, South Africa. A geological map is derived from the airborne magnetic and radiometric survey which differs significantly from the published geological map, particularly in the eastern are of the survey. There is no evidence contained within the geological data to suggest that the Greenstone Belt extends to a depth greater that 3 kilometers. The major geological constituents of the Barberton mountain land displays distinctive and diagnostic radiometric signatures, enabling accurate lithologic discrimination. 63 refs

    Magnetotelluric (MT) measurements in areas with electromagnetic (EM) noise sources such as electric fences, power and railway lines pose severe challenges to the standard processing procedures. In order to significantly improve the data quality advanced filtering and processing techniques need to be applied. The presented 5-component MT data set from two field campaigns in 2009 and 2010 in the Barberton/Badplaas area, South Africa, was acquired within the framework of the German-South African geo-scientific research initiative Inkaba yeAfrica. Approximately 200 MT sites aligned along six profiles provide a good areal coverage of the southern part of the Barberton Greenstone Belt (BGB). Since it is one of the few remaining well-preserved geological formations from the Archean, it presents an ideal area to study the tectonic evolution and the role of plate tectonics on Early Earth. Comparing the electric properties, the surrounding high and low grade metamorphic rocks are characteristically resistive whereas mineralized shear zones are possible areas of higher electrical conductivity. Mapping their depth extension is a crucial step towards understanding the formation and the evolution of the BGB. Unfortunately, in the measurement area numerous noise sources were active, producing severe spikes and steps in the EM fields. These disturbances mainly affect long periods which are needed for resolving the deepest structures. The Remote Reference technique as well as two filtering techniques are applied to improve the data in different period ranges. Adjusting their parameters for each site is necessary to obtain the best possible results. The improved data set is used for two-dimensional inversion studies for the six profiles applying the RLM2DI algorithm by Rodi and Mackie (2001, implemented in WinGlink). In the models, areas with higher conductivity can be traced beneath known faults throughout the entire array along different profiles. Resistive zones seem to correlate

  6. Archean Surface Environments and Komatiitic Volcanism: Evidence From the Barberton Greenstone Belt, South Africa

    The Barberton Greenstone Belt (BGB) includes a stratigraphic succession 10-15 km thick with at least three major intervals dominated by komatiitic rocks totaling about five kilometers in aggregrate thickness that formed over an interval of approximately 200 million years (3.48 to 3.28 Ga). Significant aspects of the mid- Archean surface environment must have been controlled by the localized build-up of komatiitic landforms, perhaps unique tectonic styles associated with komatiitic volcanism, as well as the chemically highly reactive Mg-rich mineral and glass phases as they were deposited in contact with the Archean atmosphere and hydrosphere. The 3.48 Ga Komati Formation is composed of komatiitic and minor basaltic flow rocks, 3.5 km thick, without any sedimentary interbeds or stratiform zones of alteration that might suggest pauses in volcanism. We suggest this may represent a time interval as short as 105 years. These lavas were likely deposited in submarine lava fields of large dimensions and perhaps well away from the high heat flows associated with vent areas. There is no compelling evidence to support either a mid-oceanic rift or subduction zone tectonic setting. However, it is clear that this was a geologic environment removed from the input of continent-derived sediment. The 3.29 Ga Weltevreden Formation, over 3 km in stratigraphic thickness in places, also appears to have formed over a very short time span, with little or no deposition of sediment. Unlike the Komati Formation, abundant komatiitic tuffs are interbedded with the lavas and these may document environments somewhat more proximal to volcanic vents for the Weltevreden Formation. By contrast, the 0.6-1.0 km thick Mendon Formation is composed of six or more distinctive members that each include komatiitic lava flows capped by carbonate and silica-enriched alteration zones and sedimentary cherts. The base of the formation is 3.33 Ga, several units in the interior are 3.30 Ga, and conformable cherts

    This paper reports that South Africa's main reason for entering the international nuclear market is, and always has been, to sell its uranium abroad. From 1939-45 South Africa took part in the war against Nazi Germany, and the South African government of the time sought to help the Allied war effort in all ways that were practical. Later, during the Cold War, it tried to help build up the West's nuclear arsenal. In 1944, the British government secretly asked General Smuts---prime minister of South Africa since 1939 and a member of Churchill's War Cabinet---to survey South Africa's deposits of uranium. The survey, carried out with U.S. and British help, showed that the deposits were large, generally low-grade, but, in most cases, associated with gold and therefore could be profitably mined. In 1951, South Africa became a significant producer, with lucrative contracts for the sale of all its output to the U.S.-U.K.-Canada Joint Development Agency and one of the three main suppliers to the U.S. nuclear weapons program. In time, government controls eased and uranium production and marketing became a purely commercial operation

  8. Tourmaline mineralization in the Barberton greenstone belt, South Africa: early Archean metasomatism by evaporite-derived boron.

    Tourmaline-rich rocks are common in the low-grade, interior portions of the Barberton greenstone belt of South Africa, where shallow-marine sediments and underlying altered basaltic and komatiitic lavas contain up to 50% tourmaline. The presence of tourmaline-bearing rip-up clasts, intraformational tourmaline pebbles and tourmaline-coated grains indicate that boron mineralization was a low-temperature, surficial process. The association of these lithologies with stromatolites, evaporites, and shallow-water sedimentary structures and the virtual absence of tourmaline in correlative deep-water facies rocks in the greenstone belt strengthens this model. Five tourmaline-bearing lithologic groups (basalts, komatiites, evaporite-bearing sediments, stromatolitic sediments, and quartz veins) are distinguished based on field, petrographic, and geochemical criteria. Individual tourmaline crystals within these lithologies show internal chemical and textural variations that reflect continued growth through intervals of change in bulk-rock and fluid composition accompanying one or more metasomatic events. Large single-crystal variations exist in Fe/Mg, Al/Fe, and alkali-site vacancies. A wide range in tourmaline composition exists in rocks altered from similar protoliths, but tourmalines in sediments and lavas have similar compositional variations. Boron-isotope analyses of the tourmalines suggest that the boron enrichment in these rocks has a major marine evaporitic component. Sediments with gypsum pseudomorphs and lavas altered at low temperatures by shallow-level brines have the highest delta 11B values (+2.2 to -1.9%); lower delta 11B values of late quartz veins (-3.7 to -5.7%) reflect intermediate temperature, hydrothermal remobilization of evaporitic boron. The delta 11B values of tourmaline-rich stromatolitic sediments (-9.8 and -10.5%) are consistent with two-stage boron enrichment, in which earlier marine evaporitic boron was hydrothermally remobilized and vented in

    The New Consort Gold Mine in the Palaeo- to Mesoarchaean Barberton greenstone belt, South Africa is one of the oldest recognized orogenic gold deposits on Earth. The gold mineralization is hosted by discrete mylonitic units that occur at, or close to, the contact between the mafic and ultramafic volcanic rocks of the c. 3,280 Ma Onverwacht Group and the mainly metasedimentary rocks of the overlying c. 3,260-3,230 Ma Fig Tree Group. This contact, locally referred to as the Consort Bar, formed during ductile D1 imbrication of the metavolcanosedimentary sequence and predates the main stage of the gold mineralization. The imbricate stack is situated in the immediate hanging wall of the basal granitoid-greenstone contact along the northern margin of the greenstone belt. It is characterized by a condensed metamorphic profile in which the metamorphic grade increases from upper greenschist facies conditions (510-530°C, 4 kbar) in rocks of the Fig Tree Group to upper amphibolite facies grades (600-700°C, 6-8 kbar) in the basal Onverwacht Group. Detailed structural and petrological investigations indicate that the Consort Bar represents a major structural break, which is largely responsible for the telescoping of metamorphic isograds within the structural sequence. Two stages of mineralization can be distinguished. Loellingite, pyrrhotite, and a calc-silicate alteration assemblage characterize an early high-T mineralization event, which is restricted to upper amphibolite facies rocks of the Onverwacht Group. This early mineralization may correlate with the local D1 deformation. The second and main stage of gold mineralization was associated with renewed ductile shearing during D2. The D2 deformation resulted in the reactivation of earlier structures, and the formation of a NNW trending, steeply dipping shear zone system, the Shires Shear Zone, which separates two regional SE plunging D1 synclines. The mineralized shear zones are intruded by abundant syn-kinematic pegmatite

    The impact history of the Early Archean Earth is not well documented. The oldest known impact structure is about 2 Ga years old; impact-related signatures in Precambrian rocks are scarce. The possible impact signature might be the Archean spherule layers that occur in the Barberton Greenstone Belt (BGB), Kaapvaal Craton, South Africa, and in the Pilbara Craton Western Australia, with ages of 3.2-3.4 and around 2.5 Ga [1]. These spherules were interpreted as impact-generated and ballistically emplaced silicate melt droplets [2]. This study is focused on petrographic and mineralogical characteristics from a set of newly drilled Archean spherule layers in drill core CT3 from the northeastern part of the BGB. The investigation of the three main intervals (A, B, and C, which include 2, 13, and 2 individual spherule layers, respectively) within CT3, contains the classification of spherules based on their shapes, textural features, deformation types, and mineral content. All of the intervals show spherule variation in those features. Therefore, the classification helps to understand if the spherules underwent processes such as tectonic deformation or if multiple impact events occurred in the area, which both might a reason of spherule layer duplications. The aim of the work is to differentiate various spherule types and the groundmasses in which they are embedded. The spherules within 17 identified spherule layers have been examined by optical microscopy (polarized and reflected) and secondary electron microscopy and were classified by shape and textural features. Subsequently, mineral phases and the chemical composition of the spherules and their matrices were investigated by using electron microprobe analysis. Regarding the shapes of the spherules they were divided into two main groups: undeformed and deformed. Undeformed spherules have spherical to ovoid as well as tear-drop shapes; deformed spherules were further subdivided into three main groups; flattened, crushed

    A project study, undertaken by the Geology Division of the AEB, on the correlation between airborne magnetic and radiometric data covering a portion of the Damara Mobile Belt in South West Africa, has revealed that all the known occurrences of uranium in late- to post-tectonic leucogranite (alaskite) of the Damara orogeny are associated with negative geomagnetic anomalies. Although the uranium occurrences themselves do not display marked geomagnetic anomalies, their immediate geological environment is characterised by the negative anomalies, which are semi-regional in extent. To investigate the origin of these anomalies, the Atomic Energy Board and the Geological Survey of South Africa undertook a palaeomagnetic study of the area. Oriented cores were taken from 31 sites in the mobile belt, 18 of which were selected within the negative magnetic zones, mostly in close association with known uraniferous alaskitic granites. Palaeomagnetic evidence suggests that the negative geomagnetic anomalies are associated with a remanent magnetisation, resulting from the Damara orogenic event, whose direction is removed from the earth's present field and which has affected rocks of the Nosib Group. Absence of this stable remanent direction in rocks stratigraphically overlying the Nosib Group accounts for the distinctive geomagnetic signature, in the form of negative anomalies, of the Nosib Group. It is this signature which can be used in airborne surveys to identify rocks of the Nosib Group outcropping, or of shallow suboutcrop, in anticlinal or dome-like structures. Since the uraniferous alaskites are mostly confined stratigraphically to the Nosib Group, the negative geomagnetic anomalies form an important prospecting criterion as they may be used to delineate target areas for further exploration in areas covered by sand, scree and duricrust deposits [af

    The Barberton Granitoid-Greenstone Terrain (South Africa) preserves a complex and protracted evolution involving several events of magmatism and terrain accretion along convergent tectonic boundaries. Recent studies propose that the main period of tectonic accretion and arc-related magmatism is linked to a system of divergent subduction zones above which voluminous TTG magmas were emplaced between ca. 3236 and 3227 Ma. Our structural and LA-ICP-MS U-Pb geochronology study along the southeastern margin of the Barberton Greenstone Belt (BGB) ties the waning stages of this TTG magmatism to a short (ca. BGB. The timing of the granodiorite emplacement also constrains a minimum age for the deposition of the Moodies Group clastic sediments, which for much of the southern and southeastern parts of the BGB must have happened before ca. 3228 Ma. 3205 ± 9 Ma subvolcanic dykes intruded into the granodiorite complex indicate that the period of exhumation and cooling of the crystalline rocks along the extensional detachment was relatively short (<30 Ma), between 3228 and 3205 Ma. Our observations combined with previously published structural data from the northwestern and southern margin of the belt suggest that the main mechanism of large-scale infolding of the supracrustal strata was shortly followed by the extension-related magmatism and subsequent, solid-state diapiric movement of the arc-related plutons.

    A provenance study of Neoproterozoic siliciclastic successions in the stratigraphically and tectonically lowermost and uppermost parts of the Pan-African Gariep Belt (Stinkfontein Subgroup and Oranjemund Group, respectively) in southwestern Africa, as well as in the Rocha Group of the Punta del Este Terrane (Dom Feliciano Belt) in Uruguay, revealed that the Oranjemund and Rocha Groups can be correlated and most likely formed in the same basin. Thus the Rocha Group is considered to represent the fill of the westernmost part of a re-activated Vendian Gariep Basin. The lower parts of the Oranjemund and Rocha Groups reflect erosion of mafic rocks, whereas the upper parts are derived from a predominantly felsic source area. Oceanic islands of within-plate geochemistry in the immediate vicinity were the most likely source of the mafic input into the lower part of the Oranjemund Group, with most of the other sediments derived from a passive continental margin, i.e. the western margin of the Kalahari Craton. Age spectra obtained by U-Pb SHRIMP analyses of detrital zircon grains from the Stinkfontein Subgroup (Port Nolloth Group), the Oranjemund Group and the Rocha Group are very similar, except for a lack of the youngest age group around 600 Ma in the Stinkfontein Subgroup. In all three units, zircon grains of 1000 – 1200 Ma dominate, with a further peak in the age distribution between 1700 and 2000 Ma. These ages compare well with the pre-Gariep basement geology in southwestern Africa, where the former age range corresponds to magmatic and high-grade metamorphic activity in the Mesoproterozoic Namaqua-Natal Belt and the latter to an extensive Palaeoproterozoic Andean-type volcanic arc (Richtersveld Terrane). Comparable ages are conspicuously absent in the basement of the Rio de la Plata Craton in South America. Derivation of the Rocha Group sediments from a similar source as the contemporaneous Oranjemund Group sediments is therefore suggested. The most likely source of

    The 3.22 Ga-old Moodies Group, representing the uppermost part of the Barberton Supergroup of the Barberton Greenstone Belt (BGB), is the oldest well-exposed, relatively unmetamorphosed, quartz-rich sedimentary unit on Earth. Moodies facies (north of the Inyoka Fault) were thought to be largely of alluvial, fluvial, deltaic or shallow-marine origin (Anhaeusser, 1976; Eriksson, 1980; Heubeck and Lowe, 1994) and in its upper part syndeformational. However, units can only locally be correlated, and the understanding of the interplay between Moodies sedimentation and deformation is thus limited. We mapped and measured Moodies units in the northern BGB. They partly consist of extensive turbiditic deepwater deposits, including graded bedding, flame structures, and slumped beds, interbedded with jaspilites. These contrast with shallow-water environments, south-facing progressive unconformities and overlying alluvial-fan conglomerates along the northern margin of the Saddleback Syncline further south. The palaeogeographic setting in which late BGB deformation was initiated therefore appears complex and cannot be readily explained by a simple southward-directed shortening event. In order to constrain Moodies basin setting before and during late-Moodies basin collapse, we correlated ~15 measured sections in the northern and central BGB. Most units below the Moodies Lava (MdL, ca. 3230.6+-6 Ma) can be correlated throughout although facies variations are apparent. Above the Moodies Lava, coarse-grained units can only be correlated through the Eureka Syncline and the Moodies Hills Block but not with the Saddleback Syncline. Fine-grained and jaspilitic units can be correlated throughout the northern BGB. Moodies below-wavebase deposition occurred largely north of the Saddleback Fault. The observations are consistent with a pronounced basin compartmentalization event following the eruption of the MdL which appeared to have blanketed most of the Moodies basin(s) in middle Moodies

    The ca. 3.53 to 3.29 Ga Onverwacht Group of the Barberton greenstone belt (BGB), South Africa records a rare sequence of exceptionally well-preserved volcanic, intrusive and volcani-clastic Paleaoarchean rocks. Numerous conflicting models exist for the geologic evolution and stratigraphy of this early Archean greenstone belt, ranging from plume-type dynamics to modern-style plate tectonics. Although much work has focussed on the komatiites of the ca. 3.48 Ga Komati Formation since their discovery in 1969, far less petrological attention has been given to the younger oceanic rock sequences of the Kromberg type-section in the mid-Onverwacht Group. In this study, we present new field observations from a detailed re-mapping of the Kromberg type-section, and combine this with high-resolution lithological observations from continuous drill core of the Barberton Scientific Drilling Project [1]. The new mapping and field observations are compared to a recent preliminary study of the Kromberg type-section [2]. A U-Pb detrital provenance study was conducted on a reworked, volcani-clastic unit in the upper Kromberg type-section for the first time. This included U-Pb age determination of 110 detrital zircons by secondary ion microprobe analyses (SIMS), providing constraints on maximum depositional age, provenance of the ocean-floor detritus, and timing for the onset of Kromberg ocean basin formation. These new zircon age data are compared to a previous U-Pb detrital zircon study conducted on the structurally underlying sediments of the ca. 3.43 Ga Noisy formation [3]. A multi-pronged petrological approach has been applied to various rock units across the Kromberg, including thermodynamic modelling techniques applied to metabasalts and metapyroxenites for PT-estimates, bulk- and in-situ isotope geochemistry providing constraints on protolith geochemistry and metamorphic history. Consequently, it is shown that this previously poorly studied Kromberg oceanic rock sequence of the

    asteroid impacts, reflected in the presence of spherule beds in the 3.2-3.5 Ga Barberton greenstone belt (BGB), South Africa, generated extreme seismic waves. Spherule bed S2 provides a field example. It locally lies at the contact between the Onverwacht and Fig Tree Groups in the BGB, which formed as a result of the impact of asteroid (possibly 50 km diameter). Scaling calculations indicate that very strong seismic waves traveled several crater diameters from the impact site, where they widely damaged Onverwacht rocks over much of the BGB. Lithified sediments near the top of the Onverwacht Group failed with opening-mode fractures. The underlying volcanic sequence then failed with normal faults and opening-mode fractures. Surficial unlithified sediments liquefied and behaved as a fluid. These liquefied sediments and some impact-produced spherules-filled near-surface fractures, today represented by swarms of chert dikes. Strong impact-related tsunamis then swept the seafloor. P waves and Rayleigh waves from the impact greatly exceeded the amplitudes of typical earthquake waves. The duration of extreme shaking was also far longer, probably hundreds of seconds, than that from strong earthquakes. Dynamic strains of ˜10-3 occurred from the surface and downward throughout the lithosphere. Shaking weakened the Onverwacht volcanic edifice and the surface layers locally moved downhill from gravity accommodated by faults and open-mode fractures. Coast-parallel opening-mode fractures on the fore-arc coast of Chile, formed as a result of megathrust events, are the closest modern analogs. It is even conceivable that dynamic stresses throughout the lithosphere initiated subduction beneath the Onverwacht rocks.

    The ca. 3.5 - 3.1 Ga Barberton greenstone belt (BGB) in the Kaapvaal Craton of South Africa, contains some of the world's best preserved sequences of volcano-sedimentary and mafic-ultramafic rocks representative of the Paleoarchean. These rocks provide a unique opportunity to investigate dynamic environments and possible evidence for life on the young Earth. Evidence for early microbial life has been argued to be preserved in silicified marine sediments (cherts) and subseafloor pillow lavas of the upper Onverwacht Group of the BGB. This study will focus on the ca. 3.472 - 3.334 Ga Hooggenoeg, Noisy and Kromberg Formations argued to contain textural, geochemical and isotopic evidence for the oldest traces of subseafloor life on Earth. These include filamentous titanite microtextures as candidate 'ichnofossils', X-ray maps of carbon linings associated with these microtextures and negative carbon stable isotope ratios in Archean pillow lava rims (Furnes et al., 2004, 2008; Banerjee et al., 2006). Based on previously reported similarity between these titanite microtextures and partially mineralized microtubes found in altered in-situ oceanic crust, a complex 'bioalteration' model has been proposed, involving microbial-mediated alteration of basaltic glass. Despite numerous claims for the exceptional preservation of early subseafloor alteration in the proposed 'Biomarker' type-section, constraints on the nature and timing of low-temperature alteration are not available for the Hooggenoeg Formation. In this talk, new field and petrological data from the mafic-ultramafic Kromberg, volcano-sedimentary Noisy, and dominantly mafic Hooggenoeg Formations in the southeastern part of the Onverwacht Group anticline are presented. Thermodynamic modelling provides the first metamorphic constraints on low-temperature alteration conditions preserved in the Hooggenoeg pillow metabasites. This includes a new quantitative microscale mapping approach that characterizes metamorphic

    South African President F. W. de Klerk made headlines on March 24 when he admitted to a joint session of parliament that South Africa had once had a supply of nuclear weapons; six of seven planned devices had been completed. South African spokesmen had previously said that Pretoria was capable of building weapons, but they had remained deliberately vague about whether or not any had been built. According to de Klerk, the weapons were dismantled before South Africa signed the Nuclear Non-Proliferation Treaty on July 10, 1991. De Klerk's revelation came in response to charges by the African National Congress and U.S. government officials that South Africa had possibly hidden atomic bomb components and manufacturing plants and that it had been evasive about its stockpile of weapon-grade uranium. A more complete discussion of de Klerk's disclosure and events leading to the admission are explored in this article

  7. Carbonaceous matter and putative microfossils of the mid-Archean Kromberg type-section re-visited, Barberton Greenstone Belt, South Africa

    2014-05-01

    Silicified seafloor sediments of the Kromberg Formation from the Onverwacht Group of the Barberton greenstone belt (BGB), South Africa, have been argued to contain some of the world's oldest preserved carbonaceous microfossils. Previous studies of these cherts have reported filamentous, spheroidal and ellipsoidal microfossils in thin-section (Walsh 1992); and bacteriomorph like structures in HF-etched samples (Westall et al. 2001). These microtextural studies however, lack supporting in-situ geochemical data, and are hampered to some degree by re-mobilisation of the carbonaceous matter (Van Zuilen et al. 2007). In light of these concerns, and ongoing debates surrounding carbonaceous remains in other Archean cherts (e.g., W Australia), further in-situ data from the Kromberg is required to positively identify carbonaceous matter of biogenic origin. New data will also help to address outstanding questions regarding the relative contribution of benthic versus planktonic microorganisms, and the putative microbial metabolisms involved. This study focuses on surface samples and drill core from the Barberton Scientific Drilling Programme, (BSDP, Grosch et al. 2009) from the southeastern limb of the Onverwacht anticline of the BGB. We sampled the Footbridge chert and a second chert horizon in drill core KD1 of the BSDP in the upper Kromberg Fm; and surface outcrops of two black cherts from the lower Kromberg Fm. Sedimentological logging reveals horizons rich in volcaniclastics with interbedded finely laminated grey-black chert, also intrusive black cherts, and sulphide rich horizons. The TOC of the sampled cherts is 1.24 to 5.40 wt%. Preliminary bulk carbon isotope values range from δ13C -21.1 to -35.3o values that are consistent with organic matter produced by anoxygenic photosynthesis. Microfabrics preserved in the Kromberg cherts include, primary wispy-laminated carbonaceous films suggesting compaction of early carbonaceous laminae. Also large composite carbonaceous

    2012-12-01

    This study presents a multi-disciplinary petrological approach applied to surface samples and a total of 800 m of scientific drill core that furthers our understanding of the geologic evolution of the ca. 3.5 to 3.2 Ga Onverwacht Group of the Barberton greenstone belt (BGB), South Africa. Detrital zircon grains in coarse (diamictite) to fine-grained clastic sedimentary rocks of the Noisy formation (drill core KD2a) that unconformably overlies the volcanic ca. 3472 Ma Hooggenoeg Formation, are investigated by laser ablation LA-ICP-MS to constrain their 207Pb/206Pb ages for depositional age and provenance. A wide range in 207Pb/206Pb ages between ca. 3600 and 3430 Ma is reported, corresponding to surrounding TTG plutons and the ca.3667-3223 Ma Ancient Gneiss Complex. The youngest detrital zircon grain identified has an age of 3432 ± 10 Ma. Given the short time interval for a major change in geologic environment between ca. 3472 Ma and ca. 3432 Ma, it is argued here, that the Noisy formation is the earliest tectonic basin in the BGB, which developed during major tectonic uplift at ca. 3432 Ma. In the overlying ca. 3334 Ma Kromberg type-section, application of a chlorite thermodynamic multi-equilibrium calculation, dioctahedral mica hydration-temperature curve and pseudosection modelling, indicates a wide range in metamorphic conditions from sub-greenschist to the uppermost greenschist facies across the Kromberg type-section. A central mylonitic fuchsite-bearing zone, referred to as the Kromberg Section Mylonites, records at least two metamorphic events: a high-T, low-P (420 ± 30oC, BGB and is used to test current models of mid-Archean biogeochemical sulfur cycling. In-situ δ34SCDT and Δ33S values of volcanic, detrital, diagenetic and hydrothermal pyrite of the Kromberg and Noisy Formations are presented. The Kromberg cherts and mafic-ultramafic hydrothermal vein pyrites exhibit Δ33S of -0.20 to +2.50‰, and δ34SCDT from -6.00 to +1.50‰ recording mixing

    2011-01-01

    One of Jupiter's most dominant features, the South Equatorial Belt, has historically gone through a "fading" cycle. The usual dark, brownish clouds turn white, and after a period of time, the region returns to its normal color. Understanding this phenomenon, the latest occurring in 2010, will increase our knowledge of planetary atmospheres. Using the near infrared camera, NSFCAM2, at NASA's Infrared Telescope Facility in Hawaii, images were taken of Jupiter accompanied by data describing the circumstances of each observation. These images are then processed and reduced through an IDL program. By scanning the central meridian of the planet, graphs were produced plotting the average values across the central meridian, which are used to find variations in the region of interest. Calculations using Albert4, a FORTRAN program that calculates the upwelling reflected sunlight from a designated cloud model, can be used to determine the effects of a model atmosphere due to various absorption, scattering, and emission processes. Spectra that were produced show ammonia bands in the South Equatorial Belt. So far, we can deduce from this information that an upwelling of ammonia particles caused a cloud layer to cover up the region. Further investigations using Albert4 and other models will help us to constrain better the chemical make up of the cloud and its location in the atmosphere.

    Stratigraphic and geologic interpretations of komatiitic flows and tuffs in the Barberton greenstone belt (BGB) are complicated by structural complexity, facies changes, and temporal repetition of lithofacies. Here we describe new data on the compositions of flows and tuffs and U/Pb ages that correlate existing and proposed new members of the Mendon Formation across the BGB. The Mendon Formation includes from 300 to >1000 m of komatiite, komatiitic tuff, and carbonaceous-to-ferruginous chert that represent the uppermost Onverwacht Group south of the Inyoka Fault. Our new data confirm that the Weltevreden Formation, the uppermost Onverwacht Group north of the Inyoka Fault, is correlative with the upper members of the Mendon Formation. The conformably overlying Fig Tree Group is composed largely of lithic sandstones and dacitic volcaniclastic rocks likely representing uplift and volcanism within a magmatic arc. Thus the Onverwacht to Fig Tree Group transition may represent a profound change from plume to plate tectonics. Recent studies have also demonstrated the importance of large asteroidal impacts near the Onverwacht-Fig Tree contact, two in the Mendon Formation and two in the lower Fig Tree Group spanning a 50 myr interval, suggesting a possible link between impacts and this tectonic transition. The compositional change from komatiitic to dacitic ash is moderately abrupt and near the S2 impact layer. However, at least five felsic ash layers are recognized in the Mendon Formation, and several komatiitic ash layers occur above S2 in the lowest Fig Tree Group. A preliminary compilation of the new data with that of previous studies suggests: 1) the Mendon Formation has an extreme diversity of primary komatiitic compositions, but also includes thin felsic ash layers, 2) no komatiitic flows have been identified in the Fig Tree Group but several komatiitic ash layers occur associated with spherule bed S2, 3) major faults in the south-central BGB isolate sections of the

    The National AIDS Convention in South Africa (NACOSA) in October 1992 was the first real attempt to address HIV/AIDS. In Soweto, government, the African National Congress, nongovernmental organizations, and organized industry and labor representatives worked for 2 days to develop a national plan of action, but it did not result in a united effort to fight AIDS. The highest HIV infection rates in South Africa are among the KwaZulu in Natal, yet the Inkatha Freedom Party did not attend NACOSA. This episode exemplifies the key obstacles for South Africa to prevent and control AIDS. Inequality of access to health care may explain why health workers did not diagnose the first AIDS case in blacks until 1985. Migrant labor, Bantu education, and uprooted communities affect the epidemiology of HIV infection. Further, political and social polarization between blacks and whites contributes to a mindset that AIDS is limited to the other race which only diminishes the personal and collective sense of susceptibility and the volition and aptitude to act. The Department of National Health and Population Development's voluntary register of anonymously reported cases of AIDS specifies 1517 cumulative AIDS cases (October 1992), but this number is low. Seroprevalence studies show between 400,000-450,000 HIV positive cases. Public hospitals cannot give AIDS patients AZT and DDI. Few communities provided community-based care. Not all hospitals honor confidentiality and patients' need for autonomy. Even though HIV testing is not mandatory, it is required sometimes, e.g., HIV testing of immigrants. AIDS Training, Information and Counselling Centers are in urban areas, but not in poor areas where the need is most acute. The government just recently developed in AIDS education package for schools, but too many people consider it improper, so it is not being used. The poor quality education provided blacks would make it useless anyhow. Lifting of the academic boycott will allow South African

    Archean spherule layers, resulting from impacts by large extraterrestrial objects, to date represent the only remnants of the early meteorite, asteroid, and comet bombardment of the Earth. Only few Archean impact debris layers have been documented, all of them embedded in the 3.23-3.47 billion year old successions of the Barberton Greenstone Belt (BGB) in South Africa and the Pilbara Craton in Western Australia. Some of them might be correlated with each other. Given the scarcity of Archean spherule deposits, four spherule layer intersections from the recently recovered BARB5 drill core from the central Barberton Greenstone Belt, analyzed in this study, provide an opportunity to gain new insight into the early terrestrial impact bombardment. Despite being hydrothermally overprinted, siderophile element abundance signatures of spherule-rich samples from the BARB5 drill core, at least in part, retained a meteoritic fingerprint. The impact hypothesis for the generation of the BARB5 spherule layers is supported by correlations between the abundances of moderately (Cr, Co, Ni) and highly siderophile (Re, Os, Ir, Pt, Ru and Pd) elements, whose peak concentrations and interelement ratios are within the range of those for chondrites. Rhenium-Osmium isotope evidence further support the impact hypothesis. Collectively, this study provides evidence for extraterrestrial admixtures ranging between ∼40 and up to 100% to three of the four analyzed BARB5 spherule layers, and a scenario for their genesis involving (i) impact of a chondritic bolide into a sedimentary target, (ii) varying admixtures of meteoritic components to target materials, (iii) spherule formation via condensation in an impact vapor plume, (iv) transportation of the spherules and sedimentation under submarine conditions, followed by (v) moderate post-impact remobilization of transition metals and highly siderophile elements.

    The occurrence of Early Archean barite deposits is intriguing since this type of sediment requires high availability of dissolved sulfate (SO42-), the oxidized form of sulfur, although most authors argued that the Archean eon was dominated by reducing conditions, with low oceanic sulfate concentration (state of the paleo-atmosphere and -oceans, we examined Fe and S isotope compositions in a sedimentary sequence from the 3.2 Ga-old Mendon and Mapepe formations (Kaapvaal craton, South Africa), recovered from the drill-core BBDP2 of the Barberton Barite Drilling Project. Major elements were also analyzed to constrain the respective imprints of detrital vs metasomatic processes, in particular using Al, Ti and K interrelations. Bulk rock Fe isotope compositions are linked to mineralogy, with δ56Fe values varying between -2.04‰ in Fe sulfide-dominated barite beds, to +2.14‰ in Fe oxide-bearing cherts. δ34S values of sulfides vary between -10.84 and +3.56‰, with Δ33S in a range comprised between -0.35 and +2.55‰, thus supporting an O2-depleted atmosphere (<10-5 PAL). Iron isotope variations together with major element correlations show that, although the sediments experienced a pervasive stage of hydrothermal alteration, the rocks preserved a primary/authigenic signature predating subsequent hydrothermal stage. Highly positive δ56Fe values recorded in primary Fe-oxides from ferruginous cherts support partial Fe oxidation in a reducing oceanic environment (O2 < 10-4 μM), but are incompatible with a model of complete oxidation at the redox boundary of a stratified water column. Iron oxide precipitation under low O2 levels was likely mediated by anoxygenic photosynthesis, and/or abiotic photo-oxidation processes. Our results are consistent with global anoxic conditions in the 3.2 Ga-old sediments, implying that the barite deposits were most likely sourced by atmospheric photolysis of S gases produced by large subaerial volcanic events, and possibly SO42

    This speech challenges the global community to commit to reducing HIV/AIDS in Durban, South Africa, where 1 in 4 adults is infected with the virus. A commitment of resources and energy would show good faith in fairness, generate unstoppable momentum in the prevention and control of HIV/AIDS, provide a genuine renewal in the war against this disease, and set an example for other low income, resource poor, and HIV-epidemic countries. In 2000, the 13th Annual International AIDS Conference will be suitably located in Durban in a region with the highest rates of HIV/AIDS. The 1998 UNAIDS report states that 70% of those infected with HIV (21 million) are in Africa. A shift in program effort and political will would mark a turning point in the war against AIDS. There are four "P's" behind prevention and control of the HIV/AIDS epidemic: politicians, people, private sector, and programs. It is suggested that next year's conference should include political will that will become unshakable. Budgets need to be realistic. People should have unquestionable tolerance, acceptance, and generosity. Community organizations should be strengthened. Discrimination should be stopped. Science needs to be advanced. The private sector's involvement should be meaningful and supportive. Programs should be appropriate, affordable, and accessible. Many gaps need to be bridged and many people need to enlist their aid. The author urges that conference participants remember the afflicted poor and plan for a rebirth and renewal of hope.

  7. Petrography of sandstones from drill cores BARB4 and BARB5, Paleoarchean Mapepe Formation, Barberton greenstone belt, South Africa: Implications for provenance and tectonic reconstructions.

    2014-12-01

    Paleogeographic and tectonic reconstructions in the Barberton greenstone belt (BGB) are challenged by syn- and post-depositional tectonics. The Barberton Drilling Project extracted two drill cores from the sedimentary rocks of the 3.26-3.22 Ga Mapepe Formation of the Fig Tree Group. The cores were taken from the Manzimnyama Syncline (BARB4) and the Barite Valley structural belt (BARB5), which are separated by belts of faulted older Onverwacht and younger Moodies strata. Stratigraphically, there is no clear correlation of Mapape strata in these two belts. Both BARB4 and BARB5 contain 25 to 300 m thick units of lithic sandstone that may represent correlative units. A comparative provenance analysis allows testing a possible correlation and evaluating the nature of tectonic uplifts that sourced the sediments. The sandstones have experienced pervasive metasomatic alteration and most primary silicate minerals except coarse quartz have been transformed into micromosaics of microquartz, phyllosilicates, and trace impurities. The majority of framework grains are chert, impure chert, and lithic grains while monocrystalline quartz and altered feldspar are minor components. The single thick sandstone in BARB4 displays a relatively uniform framework mode with average 38.7 % total quartz, 2.4% feldspars, and 58.9 % lithics and an increasing percentage of mafic to ultramafic grains upsection. In contrast, BARB5 includes three distinct sandstones with varying framework modes. The litharenite at 0 to 95m core depth was mainly sourced from an immediately underlying dacitic tuff. The chertarenite at 320 to 390m core depth is composed of 73% carbonaceous chert grains. All grain types appear to have been derived by erosion of sedimentary and volcanic rocks of the BGB as well as penecontemporaneous volcanism. Erosion did not reach deeper-seated plutonic rocks. The framework mode of the BARB4 sandstones represents a composite of common silicified BGB rocks and resembles those of other

Author notes that South Africa is the most economically developed country in Africa, it is among dozens of major international organizations. From the point of view of the development of the system of law, legal proceedings and arbitration, South Africa is an attractive state for study. Author emphasizes that the South African Republic throughout its existence has been influenced by two legal families: Anglo-Saxon and Romano-Germanic. Therefore, it is important to note that South Africa refers to a mixed system of law. To date, South Africa has two international commercial arbitration: the Arbitration Foundation of South Africa and the Association of Arbitrators. In the conclusion author points out that the development and establishment of the centers of the arbitration fund continues: new centers are being established, and the system of procedures for dealing with cases in already established centers is being improved.

Debates around the ability of the BRICS...... to acquire this clout continue to dominate academia and the global discourse. Although the alliance is still in its nascent stage, scholarly attention is increasingly looking at its internal dynamics. The inclusion of South Africa being the smallest economy in the BRICS was indeed an effort to consolidate...... its image and unleash the developmental potential for the rest of the African continent. Comparably, South Africa is probably the least influential member of the BRICS, and this raises the following questions.

    Full Text Available South Africa’s membership of the BRICS has stirred controversy. A number of observers have argued that South Africa is too small in terms of economy and population to be considered an authentic member of this group. In this article, the author accepts that South Africa may have no place in the analytical construct that Jim O’Neill of Goldman Sachs invented in 2001, but also argues that South Africa is a valuable and legitimate member of the political construct that we know today as the BRIC(S. South Africa has the “soft power” needed to play a constructive role in the rebalancing of geopolitical power globally, and is a potential voice for the continent of Africa. However, South Africa’s position in the BRICS must be understood in terms of its own contested role as a leader in Africa; the ambiguous outcomes of the BRICS engagement with this continent; and the danger that the BRICS may become an exclusive self-selected grouping rather than a potent force for greater global equity.

    Timing the appearance of photosynthetic microorganisms is crucial to understanding the evolution of life on Earth. The ability of the biosphere to use sunlight as a source of energy (photoautotrophy) would have been essential for increasing biomass and for increasing the biogeochemical capacity of all prokaryotes across the range of redox reactions that support life. Typical proxies for photosynthesis in the rock record include features, such as a mat-like, laminated morphology (stratiform, domical, conical) often associated with bulk geochemical signatures, such as calcification, and a fractionated carbon isotope signature. However, to date, in situ, calcification related to photosynthesis has not been demonstrated in the oldest known microbial mats. We here use in situ nanometre-scale techniques to investigate the structural and compositional architecture in a 3.3 billion-year (Ga) old microbial biofilm from the Barberton greenstone belt, thus documenting in situ calcification that was most likely related to anoxygenic photosynthesis. The Josefsdal Chert Microbial Biofilm (JCMB) formed in a littoral (photic) environment. It is characterised by a distinct vertical structural and compositional organisation. The lower part is calcified in situ by aragonite, progressing upwards into uncalcified kerogen characterised by up to 1% sulphur, followed by an upper layer that contains intact filaments at the surface. Crystallites of pseudomorphed pyrite are also associated with the biofilm suggesting calcification related to the activity of heterotrophic sulphur reducing bacteria. In this anoxygenic, nutrient-limited environment, the carbon required by the sulphur reducing bacteria could only have been produced by photoautotrophy. We conclude that the Josfsdal Chert Microbial Biofilm was formed by a consortium of anoxygenic microorganisms, including photosynthesisers and sulphur reducing bacteria.

  15. U-Pb and Pb-Pb study of the Murchison Greenstone Belt and of the Evander gold-bearing basin, South Africa. Implications for the evolution of the Kaapvaal craton

    International Nuclear Information System (INIS)

    Poujol, M.

    1997-01-01

    This study presents new U-Pb and Pb-Pb isotopic data for both the Central Rand Group from the Evander Goldfield and the Murchison Greenstone Belt (Republic of South Africa). The Evander Goldfield, where no previous isotopic data have been derived, is located in the eastern side of the Witwatersrand basin. The oldest age measured is ca. 3180 Ma, while the majority of detritus falls in the range 3050-2850 Ma. New growth of zircon (or isotopic resetting of older detritus) appears to have been associated with deposition of the Ventersdorp lavas at ca. 2.7 Ga. A small proportion of the pyrite, mainly extracted from unaltered sediments in the Kimberley Reef footwall, yields ages that are in excess of the minimum depositional age of the Witwatersrand Basin. Authigenic pyrite, as well as detrital grains from highly altered portions of the Kimberley Reef, define two main events. The Pb signature of the 2370 Ma event is probably associated with burial of the basin by the upper portion of the Transvaal sequence, and suggests circulation of highly radiogenic fluids. Isotopic signatures for the 2020 Ma event are probably related to Bushveld intrusion and/or Vredefort catastrophism, and appear to be associate with a fluid that was less radiogenic. The present study shows a number of new results which support a complex, multi-stage evolution and genesis of the Au-U deposits within the Witwatersrand Basin. The Murchison Greenstone Belt constitutes one of the world's largest antimony producing areas and also hosts gold, as well as volcanogenic massive sulfide Cu-Zn mineralization and emeralds. The goal of this study is to determine the age of the belt as well as the timing of mineralization and, also, to assess the potential role of granitoids in the ore-forming processes. The data identify an episode of greenstone formation between 3.09 Ga and 2.97 Ga. Three main magmatic events are identified at ca. 2.97, 2.82 and 2.68 Ga. Pyrites associated with both Sb-Au and Cu

    The origin and development of counselling psychology in South Africa has been profoundly influenced by the country's socio-political history and the impact of apartheid. As a result of this, counselling psychologists in the country face a number of challenges and opportunities for the future. In this paper we provide a portrait of counselling psychology in South Africa by describing the current character of the specialty and the context in which South African psychologists work. We critically discuss the challenges that the specialty faces to meet the country's mental health care needs, contest the current Scope of Practice; affirm multiculturalism without essentializing or reifying race and ethnicity, and build an evidence base for community interventions in the country. We also consider how, in the future, counselling psychologists in South Africa may make a more meaningful contribution within public health and the country's health care and education systems.

    There have been extensive developments in the power supply industry in South Africa. The most evident of these has been the increase in the size of generating units. Escom has recently placed orders for 600 MW units. In South Africa, with its large indigenous reserves of cheap coal, there was no need to rush into a nuclear power programme before it would be economic and, accordingly the first serious study of nuclear power generation was not undertaken until 1966. A final aspect of power generation which is becoming very important is the control of pollution and protection of the environment

    The potential heritage of apartheid still affects energy availability in South Africa. This article describes a new Energy Policy White paper, to be presented to Parliament, which will start to rectify current inequalities. Most of the black citizens have no access to electricity, while the affluent white minority have cheap electricity readily available to them. The complexities of funding necessary changes are addressed. South Africa`s low-cost coal reserves, mined from opencast pits next to power stations, are likely to continue to be exploited. As yet the country`s solar potential is unlikely to be developed because of the availability of coal. The production of electricity and the future of liquid fuel industries are likely to remain in crisis, even after the White Paper`s implementation. (UK)

  14. Uranium in South Africa: 1985

    International Nuclear Information System (INIS)

    1986-03-01

    South Africa's participation in the nuclear industry was limited to the production of uranium and research, with minor commercial activities. The commissioning of the Koeberg Nuclear power station in 1984 placed South Africa firmly on the path of commercial nuclear power generation. A unique, locally developed uranium enrichment process will enable South Africa to be self-sufficient in its nuclear-fuel needs. Uranium has always been of secondary importance to gold as a target commodity in the exploration of the quartz-pebble conglomerates. In the Witwatersrand Basin it is estimated that in excess of R100 million was spent on exploration during 1985. This was spent primarily in the search for gold but as many of the gold reefs are uraniferous, new uranium resources are being discovered concurrently with those of gold. Uranium mineralization is present in rocks which encompass almost the whole of the geological history of South Africa. Significant mineralization is restricted to five fairly well-defined time periods. Each period is characterized by a distinct type or combination of types of mineralization. Resource estimates are divided into separate categories that reflect different levels of confidence in the quantities reported. The resource categories are further separated into levels of exploitability based on the estimated cost of their exploitation. A major part (87%) of South Africa's uranium resources is present as a by-product of gold in the quartz-pebble conglomerates of the Witwatersrand Basin. The uranium resources in the reasonably assured resources (RAR) and estimated additional resources - category I (EAR-I) catogories were 483 300 t U. Production during 1985 was 4880 t U. Although a production peaking at over 1200 t U/a is theoretically attainable, it is considered, from market projections, that a production ceilling of 10 000 t U/a would be more realistic

  16. Administrative bias in South Africa

    E S Nwauche

    2005-01-01

    Full Text Available This article reviews the interpretation of section 6(2(aii of the Promotion of Administrative Justice Act which makes an administrator “biased or reasonably suspected of bias” a ground of judicial review. In this regard, the paper reviews the determination of administrative bias in South Africa especially highlighting the concept of institutional bias. The paper notes that inspite of the formulation of the bias ground of review the test for administrative bias is the reasonable apprehension test laid down in the case of President of South Africa v South African Rugby Football Union(2 which on close examination is not the same thing. Accordingly the paper urges an alternative interpretation that is based on the reasonable suspicion test enunciated in BTR Industries South Africa (Pty Ltd v Metal and Allied Workers Union and R v Roberts. Within this context, the paper constructs a model for interpreting the bias ground of review that combines the reasonable suspicion test as interpreted in BTR Industries and R v Roberts, the possibility of the waiver of administrative bias, the curative mechanism of administrative appeal as well as some level of judicial review exemplified by the jurisprudence of article 6(1 of the European Convention of Human Rights, especially in the light of the contemplation of the South African Magistrate Court as a jurisdictional route of judicial review.

    South Africa has one of the highest per capita rates of tuberculosis (TB) incidence in the world. In 2012, the South African government produced a National Strategic Plan (NSP) to control the spread of TB with the ambitious aim of zero new TB infections and deaths by 2032, and a halving of the 2012 rates by 2016. We used a transmission model to investigate whether the NSP targets could be reached if immediate scale up of control methods had happened in 2014. We explored the potential impact of four intervention portfolios; 1) "NSP" represents the NSP strategy, 2) "WHO" investigates increasing antiretroviral therapy eligibility, 3) "Novel Strategies" considers new isoniazid preventive therapy strategies and HIV "Universal Test and Treat" and 4) "Optimised" contains the most effective interventions. We find that even with this scale-up, the NSP targets are unlikely to be achieved. The portfolio that achieved the greatest impact was "Optimised", followed closely by "NSP". The "WHO" and "Novel Strategies" had little impact on TB incidence by 2050. Of the individual interventions explored, the most effective were active case finding and reductions in pre-treatment loss to follow up which would have a large impact on TB burden. Use of existing control strategies has the potential to have a large impact on TB disease burden in South Africa. However, our results suggest that the South African TB targets are unlikely to be reached without new technologies. Despite this, TB incidence could be dramatically reduced by finding and starting more TB cases on treatment.

    In the early 1980s, the Republic of South Africa was the world's second-largest producer of uranium, and the country historically has been a major exporter of many other important mineral resources, including gold, platinum group metals, manganese, vanadium, and gem-quality diamonds. Yet political turbulence in the latter part of the decade caused economic stress on South Africa. Apartheid, the country's disenfranchisement of the black majority, put South Africa in the international spotlight. The world responded by implementing economic sanctions against South Africa, to pressure its government into change. In the past several years, South Africa has made significant progress toward ending apartheid. As a result, many US economic sanctions previously maintained against the country have been lifted. However, economic troubles continue to plague South Africa; repealing sanctions has done little to alleviate its economic and political challenges.

    Equatorial Africa has among the highest incidences of Kaposi's sarcoma (KS) in the world, thus earning the name "KS Belt." This was the case even before the HIV epidemic. To date, there is no clear evidence that HHV-8 seroprevalence is higher in this region but interpretation of the available literature is tempered by differences in serologic assays used across studies. We examined representatively sampled ambulatory adults in Uganda, which is in the "KS Belt," and in Zimbabwe and South Africa which are outside the Belt, for HHV-8 antibodies. All serologic assays were uniformly performed in the same reference laboratory by the same personnel. In the base-case serologic algorithm, seropositivity was defined by reactivity in an immunofluorescence assay or in 2 enzyme immunoassays. A total of 2,375 participants were examined. In Uganda, HHV-8 seroprevalence was high early in adulthood (35.5% by age 21) without significant change thereafter. In contrast, HHV-8 seroprevalence early in adulthood was lower in Zimbabwe and South Africa (13.7 and 10.8%, respectively) but increased with age. After age adjustment, Ugandans had 3.24-fold greater odds of being HHV-8 infected than South Africans (p Africa. These findings help to explain the high KS incidence in the "KS Belt" and underscore the importance of a uniform approach to HHV-8 antibody testing.

  19. CIVIL JUSTICE IN SOUTH AFRICA

    2016-01-01

    Full Text Available The South African adversarial system of civil procedure in the High Court owes its origin to that of England. As with all civil procedural systems, the South African system is not stagnant. Its primary sources, namely Acts of Parliament and rules of court, are constantly amended in an attempt to meet the changing needs of society. Court delay and costinefficient procedural mechanisms, however, contribute to public dismay. The High Court, in the exercise of its inherent power to regulate its process, do so with the purpose of enhancing access to justice. The advantage of the system lies in the fact that it is not cast in stone but could, subject to the Constitution of the Republic of South Africa, 1996, be developed to make it more accessible to the public whilst protecting the public’s fundamental rights entrenched in the Constitution and, in this regard, particularly the right to afair trial embedded in sec. 34 of the Constitution. This contribution gives an overview of the system with reference to the court structure, the judiciary, the process in the High Court and its underlying principles, appeals, class actions and alternative civil dispute resolution mechanisms.

    This report outlines findings and recommendations of a national pharmacovigilance workshop held in August 2012 in South Africa (SA). A survey of current pharmacovigilance activities, conducted in preparation for the meeting, identified multiple programmes collecting drug safety data in SA, with limited co-ordination at national level. The meeting resolved that existing pharmacovigilance programmes need to be strengthened and consolidated to ensure that important local safety issues are addressed, data can be pooled and compared and outputs shared more widely. Pharmacovigilance activities should inform treatment guidelines with the goal of improving patient care. A variety of pharmaco-epidemiological approaches should be employed, including nesting drug safety studies within existing sentinel cohorts and the creation of a pregnancy exposure registry. The attendees agreed on key principles that will inform a national pharmacovigilance plan and compiled a list of priority pharmacovigilance issues facing public health programmes in SA.

    2017-12-13

    This paper explores intra-regional South-South cross-border patient travel within the context of Southern Africa. South Africa, in particular, has been widely touted as one of the emerging destinations of high-end patients from the Global North alongside other destinations such as Brazil, India, Costa Rica and Thailand. Using South Africa as a case study, the paper demonstrates that South-South cross-border patient travel is far more significant than North-South patient travel both in numerical and financial terms. Every year, thousands of patients from neighbouring countries travel to South Africa in search of medical treatment for procedures that are not offered in their own countries. Despite its size and importance, the South-South flow of patients in Southern Africa is not fully understood and requires further scholarly research.

    ESCOM, at present providing for some 95% of the electricity demand, has grown from a relatively small undertaking with a total installed capacity of less than 30 MW(e) in 1922 and a capital expenditure of R15 million during the period 1923-1930, to a gigantic undertaking with a fixed-asset value of nearly R16 billion in 1984, a staff complement of more than 60 000 and an income of over R3 billion p.a. With an estimated capital-expansion programme of between 4 and 5 billion rand p.a., ESCOM is the largest single borrower on the local capital market and it exercises a strong influence on the economy. The fact that ESCOM has been able to keep electricity prices competitive, despite inflationary costs, by the efficient utilization of resources such as coal and water, has served as a driving force for economic and industrial development and has made it possible for South Africa to establish energy-intensive metallurgical industries during the seventies. Estimates of future electricity demand based on economic considerations and population growth, lead to a sustained electricity-demand growth rate in the region of 5% p.a. At this rate of growth the known extractable coal reserves will be depleted by the year 2035, and some alternative means of generating electricity will have to be utilized timeously. At present nuclear energy is the only proven alternative to coal. Depending on certain assumptions of fuel costs, escalation and interest rates, it can be shown that nuclear electricity costs, calculated over the lifetime of a nuclear power station at the coast, could be competitive with a coal-fired power station in the interior

  2. Changing Dust Provenance to the South Atlantic Since the Last Glacial Maximum and Implications for the Southern Hemisphere Wind Belts

    Science.gov (United States)

    Franzese, A. M.; Goldstein, S. L.; Hemming, S. R.

    2017-12-01

    The Southern Hemisphere Westerly Winds are known to be important for climate due to their effects on the global carbon cycle and on the global thermohaline circulation (THC). Numerous proxy records have been interpreted to indicate significant glacial to interglacial changes in the SHWW. There is no clear consensus regarding their strength and position during the Last Glacial Maximum (LGM), though most observations are consistent with an equatorward displacement of the glacial wind belts. We test this hypothesis using geochemical provenance measurements of deep-sea sediments deposited along the Mid-Atlantic Ridge between 24°S and 37°S. In the central South Atlantic, dust can be delivered from South America via the Westerlies, or from Africa via the Trade Winds. The dust sources on South America and Africa have very different geochemical signatures, making it possible to distinguish between eolian transport via the Westerlies vs. the Trade Winds. Any northward shift in the Southern Hemisphere Westerlies should increase the northward extent of a South American provenance in sediments dominated by eolian sources. We measured major and trace element concentrations, and radiogenic isotopes of Ar, Sr, Nd, and Pb on the Africa as the primary source of sediment in the north, and South American sediments being delivered to the south. Glacial sediments display a clear compositional boundary near 30°S, which likely reflects the boundary between the Westerlies and the Trade Winds. The data are therefore not consistent with northward shifted wind belts at the LGM. The observed variations in terrigenous sediment composition at these sites may, however, be consistent with an equatorward displacement of the SHWW through the deglaciation. The results may also point to changes in the continental source regions supplying dust to the atmosphere as the glaciers retreated.

    1985-01-01

    Although the industrial exploitation of radiation processing in the medical and allied fields has been successfully marketed and applied for the past two decades in South Africa, the introduction of food radurisation on an industrial level adds a completely new dimension to the marketing of this processing technique. Extensive research into the use of radiation for the treatment of various foodstuffs has been carried out by the Nuclear Development Corporation of South Africa for more than a decade, resulting in South Africa being one of the first countries where a commercial irradiator dedicated to this branch of radiation processing, was established. The marketing of this process is especially difficult due to the emotive aspects associated with radiation and man's sensitive reaction to anything pertaining to his food. This situation was made even more difficult by the general public's apprehension towards nuclear activities throughout the world. Details are given of the steps taken in South Africa to transform the unfavourable public image associated with the process. The approach proved to be very successful and greatly assisted in creating a climate whereby the public in South Africa today generally has a favourable attitude towards the radurisation of foodstuffs.

Progress is being made in offering newborn hearing screening and studies have been conducted to document these processes within South Africa. However, due to the lack of a national and holistic overview of EHDI services to date, an accurate picture of the current status of EHDI within the South African context is required. Objective To document and profile what has been published within the field of EHDI in South Africa over the last two decades (Jan 1995–Sept 2014) in order to gain a comprehensive overview of the current status and practice of screening and diagnosis in the field of paediatric hearing loss. Method A narrative review of peer-reviewed articles related to EHDI in South Africa was conducted by searching the EBSCOHOST, SCOPUS and JSTOR databases for the period January 1995 to September 2014. Results Results indicate that over the last two decades research and publications in the field of EHDI have increased considerably. These publications have revealed extensive knowledge related to paediatric hearing screening and intervention services in South Africa; however, this knowledge seems to be limited primarily to the provinces of Gauteng and the Western Cape. Furthermore, studies pertaining to diagnosis have revealed that, although much has been written on the scientific aspects on tools for diagnosis of hearing loss, there is a lack of comprehensive information on diagnostic protocols and procedures.

    Adrian D. van Breda

    2012-03-01

    Full Text Available Military social workers in South Africa have developed distinctive ways of thinking about military social work. These developments have been influenced by various contextual factors, such as the transition of South Africa to a non-racial democracy in 1994 and the establishment of a military social work research capacity. These factors contributed to new ways of thinking, such as the recognition that military social work has a mandate to facilitate organizational change and the adoption of a resilience perspective. A central development in military social work thinking in South Africa was the formulation of a Military Social Work Practice Model, which is described and illustrated in some detail. This model emphasizes binocular vision (focusing on the interface between soldiers and the military organization and four practice positions, derived from occupational social work theory. The author notes the importance of creating appropriate contexts that facilitate further developments in military social work theory.

  12. Curbing stem cell tourism in South Africa.

    Meissner-Roloff, Madelein; Pepper, Michael S

    2013-12-01

    Stem cells have received much attention globally due in part to the immense therapeutic potential they harbor. Unfortunately, malpractice and exploitation (financial and emotional) of vulnerable patients have also drawn attention to this field as a result of the detrimental consequences experienced by some individuals that have undergone unproven stem cell therapies. South Africa has had limited exposure to stem cells and their applications and, while any exploitation is detrimental to the field of stem cells, South Africa is particularly vulnerable in this regard. The current absence of adequate legislation and the inability to enforce existing legislation, coupled to the sea of misinformation available on the Internet could lead to an increase in illegitimate stem cell practices in South Africa. Circumstances are already precarious because of a lack of understanding of concepts involved in stem cell applications. What is more, credible and easily accessible information is not available to the public. This in turn cultivates fears born out of existing superstitions, cultural beliefs, rituals and practices. Certain cultural or religious concerns could potentially hinder the effective application of stem cell therapies in South Africa and novel ways of addressing these concerns are necessary. Understanding how scientific progress and its implementation will affect each individual and, consequently, the community, will be of cardinal importance to the success of the fields of stem cell therapy and regenerative medicine in South Africa. A failure to understand the ethical, cultural or moral ramifications when new scientific concepts are introduced could hinder the efficacy and speed of bringing discoveries to the patient. Neglecting proper procedure for establishing the field would lead to long delays in gaining public support in South Africa.

Unfortunately, malpractice and exploitation (financial and emotional of vulnerable patients have also drawn attention to this field as a result of the detrimental consequences experienced by some individuals that have undergone unproven stem cell therapies. South Africa has had limited exposure to stem cells and their applications and, while any exploitation is detrimental to the field of stem cells, South Africa is particularly vulnerable in this regard. The current absence of adequate legislation and the inability to enforce existing legislation, coupled to the sea of misinformation available on the Internet could lead to an increase in illegitimate stem cell practices in South Africa. Circumstances are already precarious because of a lack of understanding of concepts involved in stem cell applications. What is more, credible and easily accessible information is not available to the public. This in turn cultivates fears born out of existing superstitions, cultural beliefs, rituals and practices. Certain cultural or religious concerns could potentially hinder the effective application of stem cell therapies in South Africa and novel ways of addressing these concerns are necessary. Understanding how scientific progress and its implementation will affect each individual and, consequently, the community, will be of cardinal importance to the success of the fields of stem cell therapy and regenerative medicine in South Africa. A failure to understand the ethical, cultural or moral ramifications when new scientific concepts are introduced could hinder the efficacy and speed of bringing discoveries to the patient. Neglecting proper procedure for establishing the field would lead to long delays in gaining public support in South Africa. Understanding the dangers of stem cell tourism – where vulnerable patients are subjected to unproven stem

    To mitigate the uncertainties in assessing the geohazards and rock conditions that affect the nuclear, mining (including hydrocarbon extraction) and civil engineering activities in South Africa, the authors are working to improve the data coverage concerning the present day stress field. In principle, this implies constraining the principal compressive stresses (σ1>σ2>σ3) or at least the maximum horizontal compressive stress (σH) because knowledge of these parameters may determine the reactivation potential of known faults, or the behaviour of large excavations and wells. By contrast, much of the subcontinent is under-represented in the World Stress Map database. For this reason we have taken a number of steps, firstly by installing a compact Trillium seismic sensor at Stofkloof (Namaqualand; adjacent to the Vaalputs low and intermediate level radioactive waste disposal facility) and 1-sec sensors at Aggeneys and Koffiemeul (Bushmanland). All stations are equipped with Reftek data loggers and powered by solar panels. The data from these stations will be integrated with data from the national network to obtain focal mechanism solutions for seismic events in the Northern Cape - southernmost Namibia region (also known as the Grootvloer cluster). These neotectonic stress tensors are then combined with σH parameters obtained from calliper logs of off-shore wells and from the geometry of joints, faults and sheared fractures in palaeosols (Bushmanland), soils and calcrete (NW Free State) and aeolianites (southern Cape). We also include underground rock engineering phenomenological observations and measurements, and data in the public domain. Our data consistently indicate a NNW-SSE oriented σH (Wegener Stress Anomaly or WSA) that prevails across most of central, southern and western South Africa, Namibia up to the Ruacana hydroelectric power plant at the Angola border. However, in the Congo basin, a few earthquake focal mechanisms suggest rotation of the regional

  15. South Africa: poised for economic growth

    Zuma, J. (African National Congress (South Africa))

    1993-01-01

    South Africa is now emerging from the period of Apartheid. Elections will be held soon, but the economic damage caused by Apartheid has to be rectified. Partly this will be through an industrial strategy, and the minerals industry will play its part. The coal mining industry provides a large proportion of South Africa's exports and 90% of electricity. It is also the basis of a synfuels industry. The coal industry will continue to be an important source of exports, either directly, or as the provider of power to energy intensive industries such as aluminium production.

  16. Project Coast: eugenics in apartheid South Africa.

    Science.gov (United States)

    Singh, Jerome Amir

    2008-03-01

    It is a decade since the exposure of Project Coast, apartheid South Africa's covert chemical and biological warfare program. In that time, attention has been focused on several aspects of the program, particularly the production of narcotics and poisons for use against anti-apartheid activists and the proliferation of both chemical and biological weapons. The eugenic dimension of Project Coast has, by contrast, received scant attention. It is time to revisit the testimony that brought the suggestion of eugenic motives to light, reflect on some of the Truth and Reconciliation Commission's findings and search for lessons that can be taken from this troubled chapter in South Africa's history.

    Full Text Available Corruption in South Africa includes the private use of public resources, bribery and improper favouritism. South Africa scored 45 points out of 100 on the 2016 Corruption Perceptions Index reported by Transparency International. Corruption Index in South Africa averaged 46.97 Points from 1996 until 2016, reaching an all-time high of 56.80 Points in 1996 and a record low of 41 Points in 2011. A tenderpreneur is common corruption in South Africa. It is an individual who enriches themselves through corrupting the awarding of government tender contracts, mostly based on personal connections and corrupt relationships - although outright bribery might also take place - and sometimes involving an elected or politically appointed official (or his or her family members holding simultaneous business interests. This is often accompanied by overcharging and shoddy workmanship.

    Objectives: To record the presence of erythristic leopards in our study site (Thaba Tholo Wilderness Reserve, Mpumalanga and to collate records from across South Africa. Method: A network of camera traps was used to record individual leopards at Thaba Tholo. We also surveyed local experts, searched the popular South African press, and used social media to request observations. Results: Two out of 28 individual leopards (7.1% recorded in our study site over 3 years were of this colour morph. We obtained records of five other erythristic leopards in the North West and Mpumalanga regions, with no reports outside of this population. Conclusions: Erythristic leopards are widely dispersed across north-east South Africa, predominantly in the Lydenburg region, Mpumalanga. The presence of this rare colour morph may reflect the consequences of population fragmentation.

Despite continued monetary discipline the inflation target has not yet been met, highlighting South Africa’s price-vulnerability as a small open emerging economy and raising questions about the efficiency of monetary policy. The objectives of this paper are: (i to analyse the influence of monetary policy on inflation in the small open emerging economy of South Africa, (ii to highlight the channels other than monetary policy through which inflation can be influenced (iii to analyse the influence of international prices and the exchange rate on inflation, (iv to determine the role of the labour market on inflation, especially through wage-push dynamics and (v to determine the role of demand-pull factors on inflation.

  9. Considering barriers to investment in South Africa

    Directory of Open Access Journals (Sweden)

    KB Afful

    2014-10-01

    Full Text Available This paper examines the effect of South Africa’s economic fundamentals on net direct investment and net portfolio investment. The results suggest that the main determinants of investment in South Africa are resource prices, input productivity and the economic performance of the domestic economy. The results illustrate that net direct investment and net portfolio investment are close but not perfect substitutes. In addition, we find that an increase in labour input costs reduces both net direct investment and net portfolio investment. Further, an increase in fixed capital productivity increases net direct investment. Further, also the results illustrate that subsidies increase both net direct investment and net portfolio investment. Moreover, an increase in exports increases both net direct investment and net portfolio investment. Policy recommendations are thus proposed that may increase foreign direct investment in South Africa.

    Telemedicine includes the use of information and communication technology for education in the health sector, tele-education. Sub-Saharan Africa has an extreme shortage of health professionals and as a result, doctors to teach doctors and students. Tele-education has the potential to provide access to education both formal and continuing medical education. While the uptake of telemedicine in Africa is low, there are a number of successful and sustained tele-education programs. The aims of this study were (i) to review the literature on tele-education in South Africa, (ii) describe tele-education activities at the University of KwaZulu-Natal (UKZ-N) in South Africa, and (iii) review the development of these programs with respect to current thinking on eHealth project implementation. A literature review of tele-education in South Africa was undertaken. The development of the tele-education services at UKZ-N from 2001 to present is described. The approaches taken are compared with current teaching on eHealth implementation and a retrospective design-reality gap analysis is made. Tele-education has been in use in South Africa since the 1970s. Several forms of tele-education are in place at the medical schools and in some Provincial Departments of Health (DOH). Despite initial attempts by the National DOH, there are no national initiatives in tele-education. At UKZ-N, a tele-education service has been running since 2001 and appears to be sustainable and reaching maturity, with over 1,400 h of videoconferenced education offered per year. The service has expanded to offer videoconferenced education into Africa using different ways of delivering tele-education. Tele-education has been used in different forms for many years in the health sector in South Africa. There is little hard evidence of its educational merit or economic worth.

    Highlights: • South Africa is considering introducing a carbon tax to reduce greenhouse gas emissions. • A phased-in tax of US$30 per ton can achieve national emissions reductions targets set for 2025. • Ignoring all potential benefits, the tax reduces national welfare by about 1.2 percent in 2025. • Border carbon adjustments reduce welfare losses while maintaining emissions reductions. • The mode for recycling carbon tax revenues strongly influences distributional outcomes. - Abstract: South Africa is considering introducing a carbon tax to reduce greenhouse gas emissions. Following a discussion of the motivations for considering a carbon tax, we evaluate potential impacts using a dynamic economywide model linked to an energy sector model including a detailed evaluation of border carbon adjustments. Results indicate that a phased-in carbon tax of US$30 per ton of CO 2 can achieve national emissions reductions targets set for 2025. Relative to a baseline with free disposal of CO 2 , constant world prices and no change in trading partner behavior, the preferred tax scenario reduces national welfare and employment by about 1.2 and 0.6 percent, respectively. However, if trading partners unilaterally impose a carbon consumption tax on South African exports, then welfare/employment losses exceed those from a domestic carbon tax. South Africa can lessen welfare/employment losses by introducing its own border carbon adjustments. The mode for recycling carbon tax revenues strongly influences distributional outcomes, with tradeoffs between growth and equity

This will be explored by means of a comparative qualitative case-based analysis...... Operation’s (PSOs).

The SANDF has increasingly become a central instrument...... African Defence Force (SADF) during the apartheid era. The transition to peacemaker has imposed constraints on the use of force and required fundamental changes to the way military force is employed. South Africa’s transition has therefore transformed the international role of the SANDF. The destabilizing...

  10. Correlation of uranium geology between South America and Africa

    International Nuclear Information System (INIS)

    1986-01-01

    Acting upon the recommendation of an Advisory Group Meeting held in 1980, the IAEA organized a Working Group on the Correlation of the Uranium Geology between South America and Africa because of the tremendous geological potential for uranium and the interest showed by the Member States of the regions concerned. The report of this Working Group is now presented. The aim of this report is to provide the nuclear industry and, in particular, the countries of the region with a broad but updated outline of current development in the uranium geology and the uranium potential of Africa and South America. The scope is such that it will provide, for those not directly involved in uranium exploration in the area, a general technical summary on the regional geology and tectonics of these two continents in order that the geodynamic setting of their uranium occurrences may be correlated. With respect to the area to be covered and bearing in mind the purpose of this study, the Working Group surveyed the most relevant parts of western Gondwanaland, of which the two continents form a part. The area covered by the report extends from north of the West African Craton and the Guiana Shield to the southern end of South America and Africa; from the Amazonian Province in western Brazil and western Argentina to the central part of the West African Craton, Congo-Kasai Craton. The Andean Chain in South America and the Atlas Mountains in North Africa, which were formed by continental accretion in recent geological time and post-dated the split and drift of the two land masses, were not considered. Some of the inner portions of those cratons distant from the coastlines and for which the correlation features do not apply have also been omitted. However, certain areas of important uranium mineralization outside the main study area have been described in order to offer comparative models for future exploration elsewhere. The subject of the report is discussed under six headings: cratonic areas

  12. South Africa's refineries: waiting for Maduna

    International Nuclear Information System (INIS)

    1997-01-01

    A definitive energy policy from the new Energy Minister, Penuell Maduna, is awaited by the petroleum industry in South Africa. Some of the complexities of the South African oil market and past legacies which make the task of producing a policy difficult, are examined here. They include the allegations made initially in 1994 that oil refineries are illegally repatriating profits by paying too much for imported products. Accusations of this transfer pricing have resurfaced in the light of recent figures published by the South African Petroleum Industry Association (SAPIA) which show that the oil industry's profitability is not as high as some had presumed. However, compelling evidence for the allegations has not appeared and it is unlikely that the foreign investors in SAPIA would endanger their operations in this way. SAPIA members are key investors in the national infrastructure and make large tax contributions much needed by the treasury. In its turn, SAPIA is unhappy about the continuation of the payment of large taxpayer funded subsidies to the privatised Sasol, the South African synthetic fuel company, seeing as anti-competitive and having negative implications for the national economy. For its part Sasol argues its entitlement to the same tariff protection enjoyed by 80% of local manufacturing industries in South Africa. Some government action has been taken to reduce the subsidies though. The oil companies in SAPIA require clarity on future energy policy and deregulation before committing themselves to further heavy capital investment and Sasol also requires an end to the present uncertainties.

  13. Astronomy Education & Outreach in South Africa

    Throop, Henry B.

    2015-11-01

    Although South Africa has evolved greatly in the 20 years since the end of apartheid, it remains a very divided country. The highest-performing students are comparable in ability to those in the US and Europe, but nearly all of these students are from priveleged Afrikaaner (European) backgrounds. The vast majority of students in the country are native African, and school standards remain very low across the country. It is common that students have no textbooks, teachers have only a high school education, and schools have no telephones and no toilets. By high school graduation, the majority of students have never used a web browser -- even students in the capital of Johannesburg. And while a few students are inspired by home-grown world-class projects such as the Square Kilometer Array (SKA) and Southern African Large Telescope (SALT), most remain unaware of their existence.Despite the poor state of education in the country, students work hard, are curious, and desire information from the outside world. Astronomy is one subject in which students in rural Africa often show exceptional interest. Perhaps astronomy serves as a 'gateway science,' linking the physically observable world with the exotic and unknown.Here I report on many visits I have made to both rural and urban schools in South Africa during the 2013-2015 period. I have interacted with thousands of grade 7-12 students at dozens of schools, as well as taught students who graduated from this system and enrolled in local universities. I will present an assessment of the state of science education in South Africa, as well as a few broader suggestions for how scientists and educators in developed countries can best make an impact in Southern Africa.

    The South African health care system is embedded in a background of racial subordination and sexual violence against girls and women and of hierarchical male authority from youth to adulthood. Low wages, unemployment, urban overcrowding, inadequate sanitation, malnutrition, crime, and violence have contributed to economic and health inequality. With more health-insured whites than blacks and the proportion of gross national product spent on health care slowly increasing, two-thirds of health expenditures have been consumed by the private sector at a time when the cost of health insurance has risen to more than 3 times the rate of the consumer price index.

    There are limited data regarding the available pediatric surgical workforce in South Africa and their employment prospects on completion of their specialist training. This aim of this study was to quantify and analyze the pediatric surgical workforce in South Africa as well as to determine their geographic and sector distribution. This involved a quantitative descriptive analysis of all registered specialist as well as training pediatric surgeons in South Africa. The results showed 2.6 pediatric surgeons per one million population under 14 years. More than half (69%) were male and the median age was 46.8 years. There were however, more female surgical registrars currently in training. The majority of the pediatric surgical practitioners were found in Gauteng, followed by the Western Cape and Kwa-Zulu Natal. The majority of specialists reportedly worked in the public sector, however the number of public sector pediatric surgeons available to those without health insurance fell below those available to private patients. Interprovincial differences as well as intersectoral differences were marked indicating geographic and socioeconomic maldistribution of pediatric surgeons. Addressing this maldistribution requires concerted efforts to expand public sector specialist posts. Descriptive audit LEVEL OF EVIDENCE: IV. Copyright © 2018 Elsevier Inc. All rights reserved.

  11. The lightning climatology of South Africa

    Directory of Open Access Journals (Sweden)

    Morné Gijben

    2012-03-01

    Full Text Available In 2005, the South African Weather Service installed a state-of-the-art cloud-to-ground lightning detection network across the country. The data recorded by this network in 2006 was utilised in the development of an initial lightning climatology of South Africa. Until 2010, this climatology was based on data from a single year. This paper updates this climatology with the lightning data for the 2006–2010 period, which is the first actual lightning climatology by the South African Weather Service based on data covering 5 years. A number of different maps were created from these lightning data. These were lightning ground flash density, median peak kiloampere, percentage positive and average flash multiplicity maps. These four maps were in turn used to develop lightning intensity risk, positive lightning risk and total lightning risk maps. Analysis of the maps showed that the highest concentrations of lightning are found over the central to northern interior of the country, with areas along the northern parts of the eastern escarpment experiencing the highest flash densities and falling within the extreme risk category. Both the positive and total lightning risks are severe for almost the entire country. Only towards the west of the country does the lightning risk decrease. This lightning climatology can now be used throughout South Africa for various disciplines. It will be especially useful for setting lightning safety standards and identifying priority areas for installing lightning conductors and conducting public awareness campaigns.

  12. The uranium industry of South Africa

    International Nuclear Information System (INIS)

    McLean, C.S.

    1994-01-01

    This paper was originally published in 1954 and is reproduced in this centenary issue of the journal of the South African Institute of Mining and Metallurgy. South Africa's economy was (and is) based on mining. The early history of the uranium mining industry (until 1954) is discussed in detail, together with its status and economy. The first quantitative assessment of the uranium potential of the Witwatersrand goldfield was made in 1945 when it was reported that South Africa had one of the largest low-grade uranium fields in the world. The first metallurgical plants brought considerable benefit to the area. The process of uranium extraction was basically similar to that employed in the recovery of gold. It could be divided into the same three main headings: agitation, filtration and precipitation. It was predicted that the program, in full swing, would possibly consume as much as 20,000 tons of manganese ore a month, as the extraction process requires dioxide. It was for this reason that manganese recovery plants have been incorporated in the process. Other materials that were to be used in large quantities were lime, limestone, animal glue and water. Considering the increasing importance of uranium in the economy of the country, the question of secrecy was becoming a problem. At that time the demand for South African uranium was guaranteed by a ten-year agreement with the British and American authorities. 3 figs

  13. Biofuels and biodiversity in South Africa

    Directory of Open Access Journals (Sweden)

    Patrick J. O’Farrell

    2011-05-01

    Full Text Available The South African government, as part of its efforts to mitigate the effects of the ongoing energy crisis, has proposed that biofuels should form an important part of the country’s energy supply. The contribution of liquid biofuels to the national fuel supply is expected to be at least 2% by 2013. The Biofuels Industrial Strategy of the Republic of South Africa of 2007 outlines key incentives for reaching this target and promoting the development of a sustainable biofuels industry. This paper discusses issues relating to this strategy as well as key drivers in biofuel processing with reference to potential impacts on South Africa’s rich biological heritage.

    Our understanding of many of the broader aspects of biofuels needs to be enhanced. We identify key areas where challenges exist, such as the link between technology, conversion processes and feedstock selection. The available and proposed processing technologies have important implications for land use and the use of different non-native plant species as desired feedstocks. South Africa has a long history of planting non-native plant species for commercial purposes, notably for commercial forestry. Valuable lessons can be drawn from this experience on mitigation against potential impacts by considering plausible scenarios and the appropriate management framework and policies. We conceptualise key issues embodied in the biofuels strategy, adapting a framework developed for assessing and quantifying impacts of invasive alien species. In so doing, we provide guidelines for minimising the potential impacts of biofuel projects on biodiversity.

  17. AIDS in South Africa. Puppet power.

    Science.gov (United States)

    Friedman, G

    1992-01-01

    Blacks in South Africa see the government campaign promoting condom use to prevent AIDS as a political ruse to control population growth among Blacks. The City Health Department of Johannesburg does not use a government created poster targeted to Blacks because it implies that only Blacks have AIDS. Even though the number of AIDS cases in South Africa is lower (700 reported cases) than that of its neighbors, the number of HIV infected individuals is growing. So nongovernmental organizations are trying to overcome the division between the government and Blacks by finding alternative ways to stem the AIDS epidemic. The African Research and Educational Puppetry Programme uses Puppets Against AIDS to bridge racial, cultural, language, and educational barriers to thus educate Blacks about AIDS. It not only hopes to create and perform educational and socially valuable theater, but also to rediscover performing arts traditions in southern and central Africa. Since about 76% of the black population in rural South Africa is illiterate, the gray skinned puppets constitute an interactive and inoffensive way to communicate a serious message. Someone demonstrates how to put on a condom using a life size model which induces controversy among physicians and educated whites. Blacks in Johannesburg and surrounding townships are not offended, however. In fact, many have never seen condoms before the demonstration. The puppets emphasize that safe sex and having sex with only 1 partner can stop the spread of AIDS. Each performance also includes live African percussion and music. A narrator distributes free condoms and AIDS information brochures to the audience. Videotapes of each performance are used to evaluate audience reactions. Independent evaluation teams evaluate the impact of the performance. 1-4 day workshops on AIDS, puppet making, story development, and performing skills follow each performance.

  18. Urbanisation and women's health in South Africa.

    Pick, W; Cooper, D

    1997-03-01

    For many decades the migrant labor system and the influx control legislation in South Africa exacerbated male-dominant patterns of migration typical of Africa. In recent years, however, and especially following the easing of influx control legislation in 1986, migration in South Africa has increasingly involved women. This paper reports on a study conducted in Khayelitsha, Cape Town, which explored the relationship between urbanisation and the health of women. The objectives were to relate age, migration, length of stay in urban areas, employment status, and occupation to the health, including reproductive health, of women living in Khayelitsha. Interviews with 659 women (61 households had no senior woman) revealed that women enjoyed considerable social support through their neighbours, church organisations, and women's organisations. Women who lived in the most deprived section of Khayelitsha enjoyed more support from their neighbours but reported less satisfaction with the area in which they lived. Child-care support was poor and a considerable proportion of the women were disempowered by their male partners. More than 90 percent of the women had access to antenatal care. Recent immigrants had more pregnancies, were less aware of screening for cervical cancer, less likely to have had a Pap smear, less knowledgeable about where to have a Pap smear done, and less likely to have heard AIDS. More women were aware of AIDS (86%) than Pap smears (45%). More than half of those of childbearing age used contraception, mainly intramuscular hormones (76%). A significant proportion (53%) of the women reported that they had had their first pregnancy as teenagers and younger, less educated women were more likely to have had adolescent pregnancies. Policy makers are confronted by a compelling need to redress well-known urban-rural inequalities in health care in South Africa. Policy attention must also be given to the increasing urbanisation of women and the growing health care

    2014-09-01

    Full Text Available There are at least six Lyssavirus species that have been isolated in Africa, which include classical rabies virus, Lagos bat virus, Mokola virus, Duvenhage virus, Shimoni bat virus and Ikoma lyssavirus. In this retrospective study, an analysis of the antigenic reactivity patterns of lyssaviruses in South Africa against a panel of 15 anti-nucleoprotein monoclonal antibodies was undertaken. A total of 624 brain specimens, collected between 2005 and 2009, confirmed as containing lyssavirus antigen by direct fluorescent antibody test, were subjected to antigenic differentiation. The lyssaviruses were differentiated into two species, namely rabies virus (99.5% and Mokola virus (0.5%. Furthermore, rabies virus was further delineated into two common rabies biotypes in South Africa: canid and mongoose. Initially, it was found that the canid rabies biotype had two reactivity patterns; differential staining was observed with just one monoclonal antibody. This difference was likely to have been an artefact related to sample quality, as passage in cell culture restored staining. Mongoose rabies viruses were more heterogeneous, with seven antigenic reactivity patterns detected. Although Mokola viruses were identified in this study, prevalence and reservoir host species are yet to be established. These data demonstrate the usefulness of monoclonal antibody typing panels in lyssavirus surveillance with reference to emergence of new species or spread of rabies biotypes to new geographic zones.

    Like China, a large portion of South Africa's primary energy is sourced from coal, and is likely to remain South Africa's major source of energy for the short to medium term. It is imperative to address the environmental dimension as an integral component of coal energy considerations. This issue is discussed through energy efficiency, and South Africa's Low-Smoke Coal Programme as it pertains to the use of coal in households. South Africa is engaged on several other programmes to minimise the impact of coal on the atmospheric environment. Some of those activities have been outlined in this paper. (R.P.)

  2. Neoproterozoic collision tectonics in the Mozambique Belt of East Africa: evidence from the Uluguru mountains, Tanzania

    Science.gov (United States)

    Muhongo, Sospeter

    1994-10-01

    The fault-bounded Proterozoic metamorphic terranes lying to the E of the Tanzanian craton make up the Usagara tectonic domain and are a part of the transcontinental Mozambique Orogenic Belt (MB). The lithotectonic units in the MB of the East Africa consist of comparable rock assembles which underwent the same complex deformational history and are thought to represent large thrust sheets or nappes. Their shelf- and fore-deep terranes border the Tanzanian craton and make up the foreland terranes of the Pan-African Mozambique Belt. Granulite-gneiss nappes are ubiquitous in the orogen. Granulite-facies metamorphism, associated with recumbent folds, was due to crustal thickening, which took place during the collision between Gondwana fragments. Isotope data suggest a collision (and concomitant granulite-facies metamorphism) age of between 700 and 550 Ma. The orientations of planar and linear fabrics in the granulite-facies rocks of the Uluguru mountains are used to infer the relative crustal block motions during this collisional event. This Pan-African collisional event was characterized by NW-directed movements, oblique to the N-S trend of the orogen, and involved SE-directed backthrusting. The Ubendian Belt of Tanzania and the Aswa Shear Zone in Uganda and Kenya, which both bifurcate around the Tanzania craton, accommodated the tectonically thickened crust, created by the collisional event, through NW-SE sinistral strike-slip movements.

  3. Does China and Africa South-South cooperation lead to economic development in Africa?

    Directory of Open Access Journals (Sweden)

    Nonfodji, P.

    2013-03-01

    Full Text Available Since a few decades now Chinese enterprises’ investments abroad have seen a continuous and steady ascension. At first cautious and just across the Chinese national borders, these investments, slowly but surely, spread like a sheet of water that seeps into the heart of each continent on the globe. This global infiltration of Chinese companies coincides with the popularity in the use of the expression “South-South Cooperation” to characterize a type of relations between countries categorized as being “developing”. Accordingly this paper seeks to examine the role of the use of this concept as a “channel to achieve common development” in the context of Chinese enterprises’ outward direct investments in Africa adopting insights from international business production theories combined with an historical analysis of the notion of South-South Cooperation. Drawing on primary data gathered during my fieldwork in China in the period stretching from December 2011 to February 2012 and secondary data sources, it is argued that these Chinese investments supported by the Chinese government rhetoric on South-South cooperation, cannot lead to significant economic development in Africa like it has happened in China in the eighties. Rather and at most Chinese investments in Africa show some “trickle-down” effects characterised by very limited economic development in scattered localities throughout the African continent.

    2017-07-01

    Full Text Available This study was conducted to investigate the extent of ethical leadership practices in African public utilities, given the relatively high corruption reported in such institutions, with consequences of seriously constrained development of national economies and significant hindrance to good governance. Our aim was to establish potential benefits from ethical leadership in public sector agencies by analysing ethical leadership characteristics in the public sector from Botswana and South Africa. We measured ethical leadership perceptions utilizing a combination of scales in an attempt to encompass the larger breadth of ethical leadership scales found in the literature in order to determine how employees perceived their managers in terms of being moral people and moral managers. A total of 108 respondents completed questionnaires. Results indicate that there were significant differences between the perceptions of managers’ moral conduct. South African leaders were perceived as relatively weaker moral managers as compared to those in Botswana.

  13. Consumer attitudes towards radurisation in South Africa

    Van Olst, M.W.

    1985-01-01

    To gain any insight into consumer attitudes towards radurization in South Africa, it is first of all necessary to pinpoint the consumer. The consumer has to be reached at all levels and must be convinced that radurization is a harmless process. All the indications are there that South African consumer acceptance will come readily once the positive benefits of irradiated food have been adequately publicized. Label and package information create untold problems for the grocery manufacturing and packaging industry. The radiation industry cannot afford to lose consumer confidence. The question is: Must a label be attached to a radurized product or not? The results of the trial marketing campaign have shown that if the correct information is supplied at the right time, the consumer is prepared to accept irradiated food

  17. Eucalyptus and Water Use in South Africa

    Directory of Open Access Journals (Sweden)

    Janine M. Albaugh

    2013-01-01

    Full Text Available The Eucalyptus genus yields high rates of productivity and can be grown across a wide range of site types and climates for products such as pulp, fuelwood, or construction lumber. In addition, many eucalypts have the ability to coppice, making this genus an ideal candidate for use as a biofuel feedstock. However, the water use of Eucalyptus is a controversial issue, and the impacts of these fast-growing trees on water resources are well documented. Regardless, the demand for wood products and water continues to rise, providing a challenge to increase the productivity of forest plantations within water constraints. This is of particular relevance for water-limited countries such as South Africa which relies on exotic plantations to meet its timber needs. Research results from water use studies in South Africa are well documented and legislation restrictions limit further afforestation. This paper outlines techniques used to quantify the water use of eucalypt plantations and provides recommendations on where to focus future research efforts. Greater insights into the water use efficiency of clonal material are needed, as certain eucalypt clones show fast growth and low water use. To better understand water use efficiency, estimates should be combined with monitoring of stand canopy structure and measurements of physiological processes.

  19. Nuclear medicine in South Africa : current status

    International Nuclear Information System (INIS)

    Vangu, M.D.T.H.W.

    2004-01-01

    Full text: Nuclear medicine in South Africa has been a full specialty on its own since 1987. It is practiced in almost all teaching hospitals and within the private sector in larger cities. Most of the routine radiopharmaceuticals are domestically manufactured and the main isotope can be obtained from locally produced technetium generators. All the radionuclide imaging devices used in the country are imported. The main vendors are GE, Siemens and Phillips. The majority of radionuclide imaging comprises work from nuclear cardiology and nuclear oncology. Almost all the routine clinical nuclear medicine procedures are performed and some in vitro work is also done, however. Principal therapeutic agents used in the country include radioactive iodine, radioactive iodine MIBG and yttrium. The country still lacks experience in receptors imaging and radioimmunology work and no PET scanner has been purchased yet. The academic institutions are active with participation in national and international congresses and also with publications. Although much remains to be done, the future of nuclear medicine in South Africa does not appear gloomy. (author)

  15. Forecasting tourist arrivals in South Africa

    Directory of Open Access Journals (Sweden)

    Andrea Saayman

    2010-12-01

    Full Text Available Purpose: The aim of this paper is to model and forecast tourism to South Africa from the country's main intercontinental tourism markets. These include Great Britain, Germany, the Netherlands, the United States of America and France. Problem investigated: Tourism to South Africa has grown substantially since the first democratic elections in 1994. It is currently the third largest industry in the country and a vital source of foreign exchange earnings. Tourist arrivals continue to grow annually, and have shown some resilience to a number of emerging market crises, including the terrorist attacks in the USA. Business success, marketing decisions, government's investment policy as well as macroeconomic policy are influenced by the accuracy of tourism forecasts, since the tourism product comprises a number of services that cannot be accumulated. Accurate forecasts of tourism demand are paramount to ensure the availability of such services when demanded. In addition, the seasonal nature of tourism leads to a pattern of excess capacity followed by shortage in capacity. Method: Since univariate time series modelling has proved to be a very successful method for forecasting tourist arrivals, it is also the method employed in this paper. The naïve model is tested against a standard ARIMA model, as well as the Holt-Winters exponential smoothing and seasonal-non-seasonal ARIMA models. Forecasting accuracy is assessed using the mean absolute percentage error, root mean square error and Theill's U of the various models. Monthly tourist arrivals from 1994 to 2006 are used in the analysis, and arrivals are forecasted for 2007. Findings: The results show that seasonal ARIMA models deliver the most accurate predictions of arrivals over three time horizons, namely three months, six months and 12 months. Value: This paper is the first tourist arrivals forecast using South African data for the country as a whole, and therefore it forms an interesting case study

  16. AREVA in the Republic of South Africa

    International Nuclear Information System (INIS)

    2007-01-01

    South Africa opted to develop its electricity production sector in a safe and competitive manner using CO 2 free technologies in order to support its economic and social growth. The country's ambitious energy program aims to create a lasting nuclear sector generating 20 GW of electricity by 2025 mainly from super modern water reactors and PBMRs. South Africa wishes to become a world player in the nuclear energy field, thus reinforcing its position as one of the major world producers of energy. In the strategic plan for the development of a national nuclear policy unveiled in July 2007, the government's objective is to create the suitable conditions for a nuclear industry based on the most modern technologies and promote an ambitious new builds construction program. By 2030, nuclear energy should provide 30% of electricity in South Africa, from a fleet of PWRs and PBMRs. In 2007, ESKOM's Board of Directors approved a plan to re-launch the construction of electrical plants in South Africa, to reach around 80 GW by 2025 and including the construction of an additional 20 GW of nuclear-based capacity. This nuclear revival program provides for the construction of PWR nuclear power plant generating a total of 3 GWe to 3,5 GWe, to go online as of 2016, and the consideration of a fleet of PWR power plants up to 20,000 MWe in total to gradually go on line through 2025. Five sites have already been identified for the new power stations and the nuclear company to build the power plants will be selected in 2008. AREVA's Evolutionary Power Reactor (EPR) and Westinghouse's AP 1000 have been pre-selected. The Government aims to achieve the objective of encourage the participation of Public entities such as the South African Nuclear Energy Corporation (NECSA) in the uranium value chain. Such public entities shall be used to store the secured uranium supplies, as well as participate in the local beneficiation. NECSA, as the state's body responsible for research and development in

    Our recent geological survey of the basement of central and northern Madagascar allowed us to re-evaluate the evolution of this part of the East Africa-Antarctica Orogen (EAAO). Five crustal domains are recognized, characterized by distinctive lithologies and histories of sedimentation, magmatism, deformation and metamorphism, and separated by tectonic and/or unconformable contacts. Four consist largely of Archaean metamorphic rocks (Antongil, Masora and Antananarivo Cratons, Tsaratanana Complex). The fifth (Bemarivo Belt) comprises Proterozoic meta-igneous rocks. The older rocks were intruded by plutonic suites at c. 1000 Ma, 820-760 Ma, 630-595 Ma and 560-520 Ma. The evolution of the four Archaean domains and their boundaries remains contentious, with two end-member interpretations evaluated: (1) all five crustal domains are separate tectonic elements, juxtaposed along Neoproterozoic sutures and (2) the four Archaean domains are segments of an older Archaean craton, which was sutured against the Bemarivo Belt in the Neoproterozoic. Rodinia fragmented during the early Neoproterozoic with intracratonic rifts that sometimes developed into oceanic basins. Subsequent Mid- Neoproterozoic collision of smaller cratonic blocks was followed by renewed extension and magmatism. The global 'Terminal Pan-African' event (560-490 Ma) finally stitched together the Mid-Neoproterozoic cratons to form Gondwana. ?? The Geological Society of London 2011.

  18. Intra-Africa agricultural trade: A South African perspective

    Directory of Open Access Journals (Sweden)

    Y. Daya

    2006-12-01

    Full Text Available Purpose: The aim of this paper is to assess and provide an overview of the magnitude of current agricultural trade patterns between South Africa and the five leading regional economic communities (REC's in Africa. This paper also seeks to examine some of the constraints limiting greater intra-African agricultural trade. This is done in order to better understand the role South Africa currently plays and could potentially play in promoting intra-Africa trade. Design/Methodology/Approach: Trade flows between South Africa and the leading REC's are outlined and explained. Trade data and tariff data is sourced from available databases. Non-tariff barriers and other impediments to greater intra-African trade are examined with reference to available literature and discussions the authors have had with trade experts and policy makers. Findings: South Africa is the most active country in intra-Africa agricultural trade. However, it is a relationship defined predominantly on exports to Africa with a low level of imports. South Africa exports a diverse range of value added products whilst imports remain concentrated in commodities. Significant imbalances in agricultural trade between South Africa and the respective REC's continue to persist. Regional trade arrangements have fostered greater trade but significant obstacles to greater trade remain. Implications: African countries that do not invest in infrastructure and create a trade-enabling environment and diversify their production, limit their potential to the supply of one or two commodities thereby perpetuating the trend of huge trade imbalances in favour of South Africa. Originality/Value: This work provides a platform for assessing trade relationships and examining impediments to greater trade. It is also relevant in guiding future research on priority markets in Africa as export destinations and import suppliers in light of increasing regional integration initiatives and governments commitment to

  19. Nigerian tourists to South Africa: Challenges, expectations and demands

    Directory of Open Access Journals (Sweden)

    Ikechukwu O. Ezeuduji

    2013-08-01

    Research purpose: This paper investigated the challenges, demands and expectations of Nigerian tourists to South Africa. Motivation for the study: Nigeria, along with other African nations, has been identified as one of the core regional source markets with air links to South Africa. Increasing revenue generated from regional tourism is important to South African Tourism. Research design, approach and method: Descriptive statistics and Chi-square tests were used to analyse the data collected using a questionnaire survey of 320 Nigerian tourists to South Africa. Main findings: Results showed that Nigerian tourists visit South Africa mostly for the purposes of business, holiday, visiting friends and relatives, education and medical care. Challenges perceived by these Nigerian tourists visiting South Africa include long waiting time for the visa process in Nigeria, expensive cost of living in South Africa, safety and security problems, not so many airlines to choose from and expensive flight costs. Nigerian tourists mostly expect South Africans to be friendlier and have expectations of linking up with new business partners or performing transactions. They also have a strong demand for shopping, leisure and quality education. Practical/managerial implications: This study recommends a bilateral tourism relationship agreement between the Nigerian and South African governments to ameliorate the visa process; targeted marketing communications by South African Tourism toward Nigerian tourists based on study results; strong police presence and proper policing in South Africa; air transport liberalisation and low-cost carriers implementation for shared economic growth within the African region. Contribution/value-add: No former research has specifically identified Nigerian tourists’ challenges, expectations and demands whilst visiting South Africa.

    Arendse Najuwa

    2008-10-01

    Full Text Available Abstract Background Female strangulation in South Africa occurs in a context of pervasive and often extreme violence perpetrated against women, and therefore represents a major public health, social and human rights concern. South African studies that provide accurate descriptions of the occurrence of strangulation incidents among female homicide victims are limited. The current study describes the extent, distribution and patterns of homicidal strangulation of women in the four largest South African metropolitan centres, Tshwane/Pretoria, Johannesburg, Cape Town and Ethekwini/Durban. Methods The study is a register-based cross sectional investigation of female homicidal strangulation, as reported in the National Injury Mortality Surveillance System for the four cities, for the period 2001 to 2005. Crude, unadjusted female strangulation rates for age and population group, and proportions of strangulation across specific circumstances of occurrence were compiled for each year and aggregated in some cases. Results This study reports that female homicidal strangulation in urban South Africa ranges from 1.71/100 000 to 0.70/100 000. Rates have generally declined in all the cities, except Cape Town. The highest rates were reported in the over 60 and the 20 to 39 year old populations, and amongst women of mixed descent. Most strangulations occurred from the early morning hours and across typical working hours in Johannesburg and Durban, and to a lesser extent in Cape Town. Occurrences across Johannesburg, Durban and Pretoria were distributed across the days of the week; an exception was Cape Town, which reported the highest rates over the weekend. Cape Town also reported distinctly high blood alcohol content levels of strangulation victims. The seasonal variation in strangulation deaths suggested a pattern of occurrence generally spanning the period from end-winter to summer. Across cities, the predominant crime scene was linked to the domestic

  3. South Africa: the new world of disability.

    Coetzer, Pieter

    2008-01-01

    Over the past 10 years, unique business imperatives in South Africa have led to innovative risk product design, some of which are still unfamiliar to the rest of the world. The main drivers are: the unique mix of first- and third-world societies in our country, and an energetic marketing force operating in an already highly saturated insurance market. As a result, new product design has become one of the most effective ways to grow new business volumes in this competitive environment. This article reviews some of the unique products available and their advantages, target markets and disadvantages. The products that are discussed include lump sum total and permanent disability benefits, extended critical illness products, cover for impairment of function as well as risk products for people living with HIV/AIDS.

  4. Psychoanalysis in Post-Apartheid South Africa

    Directory of Open Access Journals (Sweden)

    Elda Storck-van Reenen

    2015-12-01

    Full Text Available The following paper seeks to describe the trajectory of psychoanalytic endeavours in South Africa since the political thaw of the 1990s. The first part, written by Elda Storck – van Reenen, centres on the alignment of psychoanalytic training to international standards and the formation of institutions to contain these developments. Encouraging demographic and professional diversity and addressing the deficit of personal therapy – «Selbsterfahrung» – in formal training modalities are of primary importance. The second part, written by Mary-Anne Smith, elaborates on the application of basic psychoanalytic concepts to community and outreach work in an impoverished and traumatized society. In addition, the aspiration of engaging the interest and support of governmental agencies around the value and relevance of psychoanalytic thinking for primary and preventative health care is explored.

  5. Human cystic echinococcosis in South Africa

    2012-06-01

    Full Text Available Cystic echinococcosis (CE is caused by the tapeworm, Echinococcus granulosus. The tapeworms resides in the small intestines of canids and the lifecycle involves both intermediate and definitive hosts. Humans are accidental intermediate hosts. Cystic echinococcosis is an economically important infection constituting a threat to public health, and is considered an emerging disease around the world. There are at least 10 Echinococcus strain types (G1 – G10, each exhibiting diversity of morphology, development and host range. The epidemiology of CE is poorly understood in South Africa. A retrospective data analysis of the National Health Laboratory Service (NHLS laboratory information system on echinococcosis serology, microscopy and histopathology results in eight provinces (excluding KwaZula-Natal showed an overall positivity rate in submitted diagnostic samples of 17.0% (1056/6211, with the Eastern Cape (30.4%, North West (19.0% and Northern Cape (18.0% provinces showing highest rates. The data showed considerable variability between provinces. The review also showed that most proven cases were negative on serology, implying that the actual number of patients could be underestimated. To our knowledge, no data exist about the prevalent strains of E. granulosus and this prospective study will attempt to fill that gap. The aim is to genotype strains causing the disease in South Africa. Two different polymerase chain reaction (PCR methods will be used to respectively target the 12S rRNA and nad 1 genes. To date, three samples have been genotyped as G1, G5 and G6; suggesting diversity of strains prevalent in the country, but more data is needed for a clearer picture.

    The Republic of South Africa (RSA) is home to approximately 37 million people, were the highest population density is in the central industrial area. The RSA is rich in minerals, which are the main source of national prosperity. However, the country lacks a plentiful supply of water and is subject to periodic droughts.

    The Republic of South Africa (RSA) is home to approximately 37 million people, were the highest population density is in the central industrial area. The RSA is rich in minerals, which are the main source of national prosperity. However, the country lacks a plentiful supply of water and is subject to periodic droughts. The RSA can be classified as a water stressed country, and this is the factor which has a major influence on development. The limited and variable supply of water sensitises the RSA to changes in climate, especially rainfall. Hence the RSA has a vested interest in climate change, particularly as the outputs of some current theoretical models predict a lowering of rainfall over an already drought prone central southern Africa.

  9. Paleomagnetism and tectonic evolution of the Pan-African Damara Belt, southern Africa

    McWilliams, M. O.; KröNer, A.

    1981-06-01

    Paleomagnetic results are reported from the Nosib, Otavi, and Mulden groups of the Damara Supergroup, a late Precambrian shelf sequence on the southern margin of the Congo craton in Namibia. Three magnetizations were isolated in the Nosib group samples. In order of decreasing blocking temperature they are NQ1 (n = 6 sites, λ = 28°N, ϕ = 323°E, α95 = 15°), NQ2 (n = 7 sites, λ = 51°S, ϕ = 213°E, α95 = 12°), and NQ3 (n = 13 samples, λ = 09°N, ϕ = 295°E, α95 = 13°). Overall precision of all three magnetizations upon tectonic correction suggests that they predate Pan-African (650-450 Ma) folding. Two magnetizations were isolated in the Otavi group samples, above the Nosib in stratigraphic sequence. The DC1 component of possible prefolding age (n = 4 sites, λ = 52°S, ϕ = 186°E, α95 = 35°) has been over-printed by the DC2 magnetization (n = 10 sites, λ = 55°S, ϕ = 044°E, α95 = 15°) of probable postfolding age. A single magnetization of probable pre-folding age was isolated in the overlying Mulden Group samples (n = 6 sites, λ = 12°S, ϕ = 090°E, α95 = 16°). Together with previously published paleomagnetic data from Africa, the new data showed that no great relative movements have occurred between the Congo and Kalahari cratons during the interval of Pan-African tectonism in the Damara belt (McElhinny and McWilliams, 1977). Continental collision preceded by large relative displacements and closure of a wide ocean (e.g., a Himalayan analog) is effectively ruled out for the Damara belt. We develop an alternative model consistent with the available paleomagnetic and geologic data, which invokes rifting, heating, and stretching of the lithosphere underneath the Damara belt, followed by delamination of the subcrustal lithosphere. Hot asthenospheric material rises to take the place of the detached and sinking lithospheric base, inducing subduction and interstacking of continental crust. The much thickened continental crust is partially melted

  18. Positron emitting radionuclides for South Africa

    International Nuclear Information System (INIS)

    Wynchbank, S.; Van der Walt, T.N.; Sharpey-Shafer, J.

    2004-01-01

    Full text: In South Africa there are currently two projects underway to supply and utilise positron emitting radionuclides for imaging in clinical nuclear medicine facilities. The advantages and applications of such radio nuclides are numerous and well known. However the premier initial application will be to employ 1BF, at first in the compound fluorine-18 fluorodeoxyglucose ( 18 F)-FDG, for patients with cancers and neoplasms. The two projects are sited at iThemba LABS, where production of a generator supplying 66 Ga and the provision of ( 18 F]-FDG, are in an advanced state of planning; the former already fully financed by the Innovation Fund of the National Research Foundation. The two positron emitting radionuclides, 18 F and 68 Ge, will be produced using a cyclotron induced reaction on 1802 and Ga, respectively, at iThemba LABS. The 68 Ge/ 68 Ga generator consists of an anion exchanger loaded with 68 Ge, which decays to 68 Ga. The resulting radiopharmaceuticals, ( 18 F]-FDG and 68 Ga citrate, will be produced by the Radionuclide Production Group of iThemba LABS, using well described methods. However the structures and processes to be used in the generator to provide 68 Ga are novel and will be explained. Initially provision of the CBF]-FDG will be to selected clinical medicine facilities in the Western Cape and Gauteng. It should be noted that the logistical problems of providing this radiopharmaceutical (which are much complicated by its short half life of 109.7 min) to Gauteng, were shown to be surmountable in the 1970s, by a regular delivery of 18 F between Gauteng and Cape Town, after the advent of a commercial service using jet aircraft. The obvious requirement that there should be appropriate nuclear medicine facilities to image patients, at the sites to which the positron emitting radiopharmaceuticals will be supplied, has been addressed. Proposed solutions will be outlined, in terms of a dedicated positron emission tomography (PET) camera and a gamma

  1. ACHIEVING "DECENT WORK" IN SOUTH AFRICA?

    Directory of Open Access Journals (Sweden)

    Tamara Cohen

    2012-08-01

    Full Text Available The fundamental goal of the International Labour Organisation is the achievement of decent and productive work for both women and men in conditions of freedom, equity, security and human dignity. The South African government has pledged its commitment to the attainment of decent work and sustainable livelihoods for all workers and has undertaken to mainstream decent work imperatives into national development strategies. The four strategic objectives of decent work as identified by the ILO are: i the promotion of standards and rights at work, to ensure that worker's constitutionally protected rights to dignity, equality and fair labour practices, amongst others, are safeguarded by appropriate legal frameworks; (ii the promotion of employment creation and income opportunities, with the goal being not just the creation of jobs but the creation of jobs of acceptable quality; (iii the provision and improvement of social protection and social security, which are regarded as fundamental to the alleviation of poverty, inequality and the burden of care responsibilities; and (iv the promotion of social dialogue and tripartism. This article considers the progress made towards the attainment of these decent work objectives in South Africa, using five statistical indicators to measure such progress namely: (i employment opportunities; (ii adequate earnings and productive work; (iii stability and security of work; (iv social protection; and (v social dialogue and workplace relations. It concludes that high levels of unemployment and a weakened economy in South Africa have given rise to a growing informal sector and an increase in unacceptable working conditions and exploitation. The rights of workers in the formal sector have not filtered down to those in the informal sector, who remains vulnerable and unrepresented. Job creation initiatives have been undermined by the global recession and infrastructural shortcomings and ambitious governmental targets appear

    2010-01-01

    In May 2007 the South African Cabinet approved a National Hydrogen and Fuel Cell Technologies R and D and Innovation Strategy. The strategy will focus on research, development and innovation for: i) wealth creation through high value-added manufacturing and developing platinum group metals catalysis; ii) building on the existing knowledge in high temperature gas-cooled reactors (HTGR) and coal gasification Fischer-Tropsch technology, to develop local cost-competitive hydrogen production solutions; iii) to promote equity and inclusion in the economic benefits from South Africa's natural resource base. As part of the roll-out strategy, the South African Department of Science and Technology (DST) created three Competence Centres (CC), including a Hydrogen Infrastructure Competence Centre hosted by the North-West University (NWU) and the Council for Scientific and Industrial Research (CSIR). The Hydrogen Infrastructure CC is tasked with developing hydrogen production, storage, distribution as well as codes and standards programmes within the framework of the DST strategic objectives to ensure strategic national innovation over the next fifteen years. One of the focus areas of the Hydrogen Infrastructure CC will be on large scale CO 2 free hydrogen production through thermochemical water-splitting using nuclear heat from a suitable heat source such as a HTGR and the subsequent use of the hydrogen in applications such as the coal-to-liquid process and the steel industry. This paper will report on the status of the programme for thermochemical water-splitting as well as the associated projects for component and technology development envisaged in the Hydrogen Infrastructure CC. The paper will further elaborate on current and future collaboration opportunities as well as expected outputs and deliverables. (authors)

    Project developers in South Africa are puzzled with the long process of evaluating and registering their CDM projects. In addition to other obstacles, we find that South African big businesses are rather reluctant to engage in any new business activities such as CDM projects and municipalities often lack the necessary flexibility. This offers opportunities for small-scale project developers who spot the opportunities and find creative solutions to overcome these difficulties. - Highlights: • First paper analysing the experience of small project developers in South Africa. • Project developers in South Africa are puzzled with the long process. • South African big businesses are reluctant to engage in CDM projects. • Small-scale project developers spot opportunities and find creative solutions to overcome difficulties. • Also, we saw learning processes of South African administration in support of CDM projects

  11. Investigating smallholder farmers’ exclusion from credit markets in South Africa

    2015-09-01

    Full Text Available Access to credit by smallholder farmers in South Africa has been empirically observed to be characterised by a variety constraints. This paper examines the demographic, financial and economic characteristics of smallholder farmers in order to gain a better understanding of why smallholder farmers are excluded from formal credit markets. The paper uses survey data collected from 362 smallholder farmers randomly selected from Mpumalanga and North West Provinces of South Africa. Using descriptive analysis, the paper observes that smallholder farmers have low annual turnover, low demand for credit and often with a family culture not to borrow. The paper concludes that smallholder farmers in South Africa are still financially excluded, particularly from the formal banking systems. Results of this paper demonstrate a need for a review of financial policies in favour of increasing the supply of financial services, particularly credit to smallholder farmers if South Africa is to achieve its Millenium Development Goals of employment creation and poverty alleviation.

    2011-01-01

    In developing countries, the ability to provide adequate and reliable energy supplies is a key to sustainable economic development. The aim of this report is to study the energy supply security in both Southern Africa and South America and how these regions can participate in the international effort to combat climate change. This report showed that South Africa's energy sector mostly relies on carbon intensive coal while Brazil is mainly supplied by hydroelectricity. It was found that in both countries energy needs will increase significantly due to rising demand both internally and at a regional scale. However it was also shown that both Southern Africa and South America have important hydro, solar and wind renewable resources which could enhance their electricity security while minimizing their environmental impacts. This study demonstrated that Southern Africa and South America can enhance their electricity security through the use of renewable energies but that technology and financing is needed to develop the sector.

    M.G. Collett

    2000-07-01

    Full Text Available A questionnaire, designed to obtain qualitative information on a number of variables concerning canine babesiosis (biliary fever in South Africa, was sent to 510 veterinary practices in late 1993. Of the 157 practices that responded, all were presented with cases of babesiosis and most were situated in Gauteng, the Western Cape and KwaZulu-Natal. Apart from the Western Cape, a winter-rainfall region, the prevalence of babesiosis cases in dogs was highest in summer. Most of the respondent practices treated between 1000 and 5000 sick dogs that included 100 to 500 babesiosis cases each year. Respondents identified cerebral babesiosis, enterorrhagia, 'red' or haemoconcentrated babesiosis, acute renal failure and pulmonary babesiosis or 'shock lung', amongst others, as the most prevalent forms of complicated ('atypical' babesiosis. Diminazene, imidocarb and trypan blue were the most popular antibabesials. Trypan blue was most often used in shocked patients, whereas diminazene and imidocarb were preferred when there was a high parasitaemia in the absence of shock. At least 19 antibabesial treatment regimens were used in practices. These comprised the use of single doses of antibabesial drugs; split doses with repeat injections, and combined drug variations, some of which are undesirable due to possible sterilisation of Babesia infection or potential toxicity. Side-effects were most commonly associated with imidocarb use. Ninety-six percent of respondents used supportive treatment (e.g. corticosteroids, vitamins and 'liver support' in all cases of babesiosis. The use of blood transfusion as supportive treatment varied according to practice and severity of the case. Most practices never cross-matched blood to be transfused, and transfusion reactions were rare. Diminazene was most frequently incriminated in cases where drug 'resistance' or relapses occurred. Cerebral and 'red' cases resulted in high mortality. Treatment of babesiosis costs the dog

    Africa's biggest producer of electricity Eskom, is at a crossroad. Almost 90% of South Africa's electricity is generated by coal-fired power stations. On-off plans for nuclear power seem to be 'on' again and the regulatory red tape that has thwarted independent power producers could be cut. 3 photos.

  20. 'Emerging' mycobacteria in South Africa : review article

    2009-05-01

    Full Text Available Disease can be caused by various species of the genus Mycobacterium. A number of reports, both published and unpublished, of rarely reported mycobacteria have surfaced in South Africa in the last few years. Some unusual hosts have also been involved, causing concern in some quarters.These include reports on Mycobacterium goodii in a spotted hyaena (Crocuta crocuta, M. xenopi in a ruffed lemur (Varecia variegata, M. intracellulare in wild-caught chacma baboons (Papio ursinus, the 'dassie bacillus' in free ranging rock hyrax (dassies; Procavia capensis the 'oryx bacillus' from free-ranging buffalo (Syncerus caffer and M. tuberculosis in suricates (Suricata suricatta, a domestic dog and in baboons. In this article it has been attempted to put these in context and show how improved surveillance and technologies have allowed mycobacteria to be identified to species level more easily. Most of the unusual mycobacterial species have most likely been present in the region for many years and have probably caused disease episodes before, but have been misdiagnosed. Each case must be evaluated carefully with respect to the animal species involved, the environment in which the host is found and the mycobacterial species, and operational decisions made accordingly.

  1. 'Best buys' for surgery in South Africa.

    2017-09-22

    Improving access to basic surgical interventions has great potential to improve the length and quality of life of many people in low- and middle-income countries (LMICs). However, research has shown that current access to surgical interventions is limited, and initiatives such as the Lancet Commission on Global Surgery 2030 advocate for improved access to basic surgical interventions for all. As the needs, health system context and available budgets in each country will be different, a critical component of effective local scale-up of surgical interventions will be to use tools and processes of health technology assessment (HTA). HTA has traditionally been used in high-income countries to make decisions about which medicines and devices should be available in a health system, but its central concepts, such as assessing clinical effectiveness, cost-effectiveness and feasibility, appraising all available evidence, and incorporating wider health systems objectives in decision-making, can be applied to decisons about how LMICs can best utilise basic surgical interventions from within available resources - in essence, to focus spending on the 'best buys'. As South Africa (SA) moves towards National Health Insurance (NHI), HTA functions will be strengthened. There is potential for SA to lead the practice of application of HTA to decisions about how basic surgical interventions are chosen and implemented, contributing to the success and sustainability of NHI in SA and the health of people in LMICs worldwide.

  3. Sources of household salt in South Africa.

    Jooste, Pieter L

    2005-01-01

    Marketing of non-iodized salt through unconventional distribution channels is one of the factors weakening the national salt iodization program in South Africa. The aim of this study was therefore to quantify the various sources of household salt, and to relate this information to socio-economic status. Questionnaire information was collected by personal interview during home visits from a multistage, cluster, probability sample of 2164 adults representative of the adult population. Nationally 77.7% of households obtained their table salt from the typical food shops distributing iodized salt. However, in the nine different provinces between 8 and 37.3% of households used unconventional sources, distributing mainly non-iodized salt, to obtain their household salt. These alternative sources include distributors of agricultural salt, small general dealer shops called spaza shops, in peri-urban and rural townships, street vendors and salt saches placed in the packaging of maize meal bags. Country-wide around 30% of low socio-economic households obtained their salt from unconventional sources compared to less than 5% in high socio-economic households, emphasizing the vulnerability of low socio-economic groups to the use of non-iodized salt. Intervention strategies should mobilize all role players involved in unconventional marketing channels of household salt to provide only iodized salt to consumers, as required by law.

  4. Aggression, anger and violence in South Africa

    Directory of Open Access Journals (Sweden)

    M.J. Masango

    2004-12-01

    Full Text Available This article traces the roots of aggression, anger and violence in South Africa and the rest of the world. The paper is divided into four parts: Aggression, Anger, Catharsis and Violence. As a result of violence against other human beings, especially women and children, a profound respect for human dignity has been lost. People have become extremely aggressive. The last few decades have created a culture of violence because of the suppression or oppression of feelings. The article argues that frustration yields anger that leads to violent acts. The root cause of violence is frustration, which finally (if not attended to produces anger, anxiety, conflict and the eruption of violence. Suicide bombers in Palestine and other parts of the world demonstrate this type of aggression, anger and violence. Anger, on the one hand, is a good defense mechanism. It helps people cope with frustration. Violence, on the other hand, is used as a means of dominance, especially against women and children. In a political situation it is used as a means of changing social structures.

  5. Marine fisheries monitoring programmes in South Africa

    Directory of Open Access Journals (Sweden)

    M. Mayekiso

    2010-01-01

    Full Text Available South Africa was an early leader in multidisciplinary studies of marine resources, particularly with the Benguela Ecology Programme in the 1980s and 1990s and catch records are available for some species dating back more than a century. Resources data have focused on trends in catches, fishing effort and changes in distribution and abundance of harvested resources, which often account for a major part of the structure and functioning of marine ecosystems. Data have been collected by means of fishery-dependent and fishery-independent survey techniques appropriate to each particular stock and analysed using traditional single species stock assessment techniques. The data are complemented by comprehensive information on the environment and top predators and have been analysed using trophodynamic models such as Ecopath with Ecosim. Future approaches include a shift to an ecosystem approach to fisheries monitoring and management, in an attempt to reconcile utilisation and biodiversity conservation objectives. Despite these scientific achievements, the single species approach to the management of most resources still persists, with only limited interactions between competing species or predators and prey being formally taken into account when modelling the stock dynamics and providing management advice to the authorities.

    Full Text Available The International Association for the Evaluation of Educational Achievement (IEA initiated the Second International Technology in Education Study (SITES 2006 - a large-scale comparative survey on the use of Information and Communication Technologies (ICTs in schools. The goal was to understand the pedagogical use of ICTs in schools in 22 education systems. We aim to contextualize South Africa's participation in SITES 2006 on four levels: (i the nature and structure of the South African education system, (ii a review of South Africa's participation in SITES 2006, (iii ICT infrastructure, facilities and equipment, and (iv teachers' use of ICTs for teaching and learning. SITES 2006 administered three questionnaires to school principals, technology coordinators, and mathematics and science teachers. The final sample consisted of 666 mathematics and 622 science teachers. Although most education systems collected data via the internet, South Africa was the only country that used only a paper-and-pencil data collection strategy with an average return rate of 90%. South Africa scored low on most variables, e.g. ICT infrastructure, facilities, and equipment. A large percentage of South African teachers reported their ICT incompetence. South Africa's inability to cross the boundaries of traditional learning towards the development of 21st century teaching and learning skills inhibits social and economic growth for the development of human capital.

  8. The Economic Burden of Violence against Children in South Africa

    Full Text Available The purpose of this study was to estimate the economic burden of violence against children in South Africa. We assembled summative estimates of lifetime prevalence, calculated the magnitude of associations with negative outcomes, and thereby estimated the economic burden of violence against children. According to our calculations, 2.3 million and 84,287 disability-adjusted life-years (DALYs lost in South Africa in 2015 were attributable to nonfatal and fatal violence against children, respectively. The estimated economic value of DALYs lost to violence against children (including both fatal and nonfatal in South Africa in 2015 totalled ZAR173 billion (US $13.5 billion—or 4.3% of South Africa’s gross domestic product (GDP in 2015. In addition, the reduced earnings attributable to childhood physical violence and emotional violence in South Africa in 2015 were ZAR25.2 billion (US $2.0 billion and ZAR9.6 billion (US $750 million, respectively. In addition, South Africa spent ZAR1.6 billion (US $124 million on child care and protection in fiscal year 2015/2016, many of which costs are directly related to violence against children. This study confirms the importance of prioritising violence against children as a key social and economic concern for South Africa’s future.

    Vaalputs, the South African, National Radioactive Waste Management Facility, is situated in an area of the Northern Cape Province and is operated by the Atomic Energy Corporation of South Africa Limited. Screening and site selection lasted from 1978-1984, construction took place from 1984 to 1986. The waste received is predominantly from the Koeberg nuclear power station and low and intermediate-level radioactive waste is disposed of in a near surface disposal facility in clay. Two trenches were excavated for use, one is used for concrete containers and one for other waste, mostly compressed trash in 200-liter drums. No capping of trenches has taken place as it was originally anticipated that the trenches would be capped after being filled. Much slower delivery of waste packages and other problems has led to a process of temporary capping

    South Africa is a country in the midst of transformation. Political changes within the country, and the ensuing empowerment of the black majority, have created a situation where dramatic improvements are needed in the country's infrastructure in order to enable it to meet the needs of all its people over the coming decades. Largely as a result of the international embargo placed on South Africa during the apartheid era, the South African government became heavily involved in the country's energy sector. This involvement included development of a synfuels program, price controls in the oil sector, monopolies in both upstream and downstream oil sectors, and a strong centralized electric power company. In 1994, South Africa became the eleventh member of the Southern Africa Development Community (SADC), an organization which was established in 1980 to synchronize development plans for its member countries. SADC is presently working to formulate a regional energy development plan, and coordinate technical information exchanges and joint research needs. Each of the SADC nations have also begun to develop their regional electricity grids and other parts of their energy infrastructure to plan for the growing needs of the 500 million people who live in sub-Saharan Africa.

    Full Text Available Purpose: Owing to a shortage of South African research focusing on international strategic alliances, this study aimed to determine whether the advantages and pitfalls of international strategic alliances referred to in international business publications are also applicable to South African international strategic alliances. Design/Methodology/Approach: This was a formal, empirical study that targeted the 163 South African enterprises which were members of the South African-Angolan Chamber of Commerce in 2005 and 2006. Findings: The results identified joint ventures as the most prominent mode of entry when expanding into developing countries and, with few exceptions, the findings support the advantages and pitfalls of international strategic alliances identified in other international publications. Value of the research: A great deal of international management research over the years has been focused on the importance of strategic alliances as a mode of entry, as well as on the pitfalls experienced by alliance partners, particularly in developed countries. However, the lack of such research in Africa in general and South Africa in particular means that South African enterprises must base their entry mode selection on non-South African research findings, and although this sample size was small, the lack of other Africa-specific research makes this research significant. Implications: With South Africa being the largest source of FDI into the rest of Africa, the findings of this paper show that South African enterprises can attain the advantages associated with international strategic alliances when using this mode of entry into Africa. In terms of pitfalls, the findings highlight the need for multinational enterprises to pay specific attention to the role of governments when forming strategic alliances.

  5. BioEnergy Feasibility in South Africa

    The BioEnergy Atlas for South Africa is the result of a project funded by the South African Department of Science and Technology, and executed by SAEON/ NRF with the assistance of a number of collaborators in academia, research institutions, and government. Now nearing completion, the Atlas provides an important input to policy and decision support in the country, significantly strengthens the availability of information resources on the topic, and provides a platform whereby current and future contributions on the subject can be managed, preserved, and disseminated. Bioenergy assessments have been characterized in the past by poor availability and quality of data, an over-emphasis on potentials and availability studies instead of feasibility assessment, and lack of comprehensive evaluation in competition with alternatives - both in respect of competing bioenergy resources and other renewable and non-renewable options. The BioEnergy Atlas in its current edition addresses some of these deficiencies, and identifies specific areas of interest where future research and effort can be directed. One can qualify the potentials and feasible options for BioEnergy exploitation in South Africa as follows: (1) Availability is not a fixed quantum. Availability of biomass and resulting energy products are sensitive to both the exclusionary measures one applies (food security, environmental, social and economic impacts) and the price at which final products will be competitive. (2) Availability is low. Even without allowing for feasibility and final product costs, the availability of biomass is low: biomass productivity in South Africa is not high by global standards due to rainfall constraints, and most arable land is used productively for food and agribusiness-related activities. This constrains the feasibility of purposely cultivated bioenergy crops. (3) Waste streams are important. There are significant waste streams from domestic solid waste and sewage, some agricultural

    Full Text Available The South African educational system is in a state of transformation as the Government embarks on a process of grappling with legacies of the past, whilst balancing risks and opportunities for the future. Accordingly, a new school curriculum with outcomes-based education as the fundamental building block was introduced along a sliding scale, starting in 1997. This curriculum, with a vast statistics content, has the potential to change the face of statistics education in South Africa, as statistics had previously been virtually absent from the school syllabus. This article highlights the challenges to and opportunities for optimising the teaching of statistics across all education levels in South Africa.

    This paper describes the neutron tomography investigation on archaeological artifacts from museums in South Africa. While X-rays fail to penetrate the brass matrix of the samples, neutrons can easily reveal, on a non-invasive manner, the content and structure of these precious samples. The South African Neutron Radiography (SANRAD) facility, located at the SAFARI-1 nuclear research reactor, operated by Necsa near Pretoria, South Africa, was utilized in a tomography mode during the investigations. For the 3D tomographical reconstruction of the sample, 375 projections were collected while the sample was rotated around a defined axis through 360 deg. rotation interval. The results show that the technique is able to reconstruct structural features very well and in particular, highly absorbing zones and the presence of defects in the bulk. The samples originate from collections at museums in South Africa and these investigations were the first of its kind performed in the country.

    Nuclear Energy Policy was approved in June 2008 focusing on ring-fencing nuclear activities and giving them dedication that contributes towards climate change mitigation. Contributing towards security of supply, efforts through diversification of the electricity generation mix, calls for the formation of a nuclear industry in South Africa (SA). To promote nuclear energy as an important electricity supply option, there was establishment of national industrial capability for the design, manufacture and construction of energy systems. This contribute to national program of social and economic transformation, growth and development, and Guide in the actions to develop, promote, support, enhance, sustain and monitor the nuclear energy sector in SA. Attainment of global leadership and self-sufficiency in the nuclear energy sector is a long term exercise that will control over unprocessed uranium ore for export purposes for the benefit of SA economy. There is an endeavour to implement or obtain interest in the complete nuclear fuel cycle and allow participation of public entities in the uranium value chain. Reduction of greenhouse gas emissions and skills development related to nuclear energy need to be improved. The Nuclear Energy Strategy and Implementation Plan Working Group was established in order to finalize the strategy to implement the Nuclear Energy Policy, as guided by the Country’s Integrated Resource Plan (IRP). To analyze the current legislative framework governing the nuclear sector and Identify gaps in current legislative and regulatory framework and the international legal instruments required to facilitate the decision.

    Full Text Available In the early colonial history of South Africa, horses played an important role, both in general transportation and in military operations. Frequent epidemics of African horsesickness (AHS in the 18th century therefore severely affected the economy. The first scientific research on the disease was carried out by Alexander Edington (1892, the first government bacteriologist of the Cape Colony, who resolved the existing confusion that reigned and established its identity as a separate disease. Bluetongue (BT was described for the first time by Duncan Hutcheon in 1880, although it was probably always endemic in wild ruminants and only became a problem when highly susceptible Merino sheep were introduced to the Cape in the late 18th century. The filterability of the AHS virus (AHSV was demonstrated in 1900 by M’Fadyean in London, and that of the BT virus (BTV in 1905 by Theiler at Onderstepoort, thus proving the viral nature of both agents. Theiler developed the first vaccines for both diseases at Onderstepoort. Both vaccines consisted of infective blood followed by hyper-immune serum, and were used for many years. Subsequent breakthroughs include the adaptation to propagation and attenuation in embryonated eggs in the case of BTV and in mouse brains for AHSV. This was followed by the discovery of multiple serotypes of both viruses, the transmission of both by Culicoides midges and their eventual replication in cell cultures. Molecular studies led to the discovery of the segmented double-stranded RNA genomes, thus proving their genetic relationship and leading to their classification in a genus called Orbivirus. Further work included the molecular cloning of the genes of all the serotypes of both viruses and clarification of their relationship to the viral proteins, which led to much improved diagnostic techniques and eventually to the development of a recombinant vaccine, which unfortunately has so far been unsuitable for mass production.

    African tick-bite fever, caused by Rickettsia africae and transmitted by Amblyomma ticks, is an emerging rickettsiosis in southern Africa. Because of increased tourism to this area, several cases in tourists have been reported recently. We report 13 cases of R. africae infection diagnosed in France that occurred in competitors returning from an adventure race in South Africa and compare our data with previously reported findings. Most of our patients presented with fever, headache, multiple inoculation eschars, and regional lymphadenopathies, but only 15.4% had a cutaneous rash. Diagnosis was confirmed either by isolation of R. africae from an eschar biopsy specimen or by serological methods, including cross-adsorption between R. africae and Rickettsia conorii. The purpose of this study was to raise physicians' awareness of R. africae infections in an attempt to facilitate the rapid diagnosis and treatment of imported African tick-bite fever in developed countries.

    The meta volcano sedimentary units that integrate the central Dom Feliciano Belt (DFB) represent supra crustal rocks distributed between the Granite Domain in the southeast and fore arc basins in the northwest. In this central segment, meta volcanic sedimentary sequences predominate, occurring discontinuously along 1,200 km, in a narrow NESW belt of average widths around 40 km (fig. 1). Three distinct metamorphic complexes can be distinguished. These are from north to south the Brusque, Porongos and Lavalleja Complexes. They consist of poly deformed sequences in which at least three fold phases can be distinguished associated with a mass transport to NW. The dominant foliation in most of the rocks is a peak metamorphic transposition surface S2. The regional metamorphism reached green schist facies and locally low amphibolite facies. The continuity of the individual supra crustal sequences is likely, because of strong similarities in their geotectonic setting, metamorphic history, post-depositional granitic magmatism, and geochronology. However, more evidences is required to prove such continuity and detailed comparative studies of the lithostratigraphic columns of each belt have not been carried out. Basement inliers within these belts are Paleoproterozoic (2.3 - 2.0 Ga), affected by Neoproterozoic metamorphism and granite genesis (ca. 610 +/- 10 Ma). This work presents some results of U-Pb dating of detrital zircon from the Brusque, Porongos and Lavalleja supra crustal units that make up the Dom Feliciano Belt

    2015-01-01

    Intra-regional South-South medical tourism is a vastly understudied subject despite its significance in many parts of the Global South. This paper takes issue with the conventional notion of South Africa purely as a high-end "surgeon and safari" destination for medical tourists from the Global North. It argues that South-South movement to South Africa for medical treatment is far more significant, numerically and financially, than North-South movement. The general lack of access to medical diagnosis and treatment in SADC countries has led to a growing temporary movement of people across borders to seek help at South African institutions in border towns and in the major cities. These movements are both formal (institutional) and informal (individual) in nature. In some cases, patients go to South Africa for procedures that are not offered in their own countries. In others, patients are referred by doctors and hospitals to South African facilities. But the majority of the movement is motivated by lack of access to basic healthcare at home. The high demand and large informal flow of patients from countries neighbouring South Africa has prompted the South African government to try and formalise arrangements for medical travel to its public hospitals and clinics through inter-country agreements in order to recover the cost of treating non-residents. The danger, for 'disenfranchised' medical tourists who fall outside these agreements, is that medical xenophobia in South Africa may lead to increasing exclusion and denial of treatment. Medical tourism in this region and South-South medical tourism in general are areas that require much additional research. Copyright © 2014. Published by Elsevier Ltd.

  18. Financial guarantees and public debt in South Africa

    Full Text Available A few years since the worst of the Euro sovereign debt crisis, many nations, from Cyprus to Ireland, including South Africa are re-visiting their public debt management to avert or lessen the impact of similar such happenings in the future. There are a number of studies on risk assessments of fiscal sustainability; however, few focus on contingent liabilities and even fewer on financial guarantees. In South Africa, financial guarantees have consistently comprised just above or below 50% of all contingent liabilities since the early days of majoritarian rule. In lieu of this, the paper analyses the risks posed by financial guarantees to fiscal sustainability in South Africa. We estimate the effect of financial guarantees on public debt in South Africa via the Engle Granger and causality model with quarterly time series data obtained from the South African Reserve Bank (SARB as well as the National Treasury. The data covers the April 1997 to December 2011 period. All econometric methods were executed using the statistical software package E-Views 7. We found that no long run relationship exists between national net loan debt and financial guarantees in South Africa. The pass rate of financial guarantees significantly affects its present value. The pass rate of financial guarantees has a predicting ability in determining the present value of national net loan debt. These findings may be contrary to what would be expected in the case of South Africa considering that the country is managing the issuance of financial guarantees prudently and that at present levels, there is no need for a radical policy shift. The study therefore offers a lesson to similar merging economies on the good governance of contingent liabilities.

    The Central Asian Orogenic Belt (CAOB) was the result of long-lived multi-stage tectonic evolution, including Proterozoic to Paleozoic accretion and collision, Mesozoic intracontinental modification, and Cenozoic rapid deformation and uplift. The accretionary and collisional orogenesis of its early history generated a huge orogenic collage consisting of diverse tectonic units including island arcs, ophiolites, accretionary prisms, seamounts, oceanic plateaus and micro-continents. These incorporated orogenic components preserved valuable detailed information on orogenic process and continental crust growth, which make the CAOB a key region to understanding of continental evolution, mantle-crust interaction and associated mineralization. The western CAOB refers to the west region in North Xinjiang of China and circum-Balkash of Kazakhstan, with occurrences of the spectacular Kazakhstan orocline and its surrounding mountain belts. Because orogenic fabrics of this part mostly preserve their original features caused by the interactions among the southern Siberian active margin in the north and the Tarim Craton in the south, the western CAOB can be regarded as an ideal region to study the processes of the accretionary and collisional orogenesis and associated mineralization. Since a large number of researchers have been working on this region, research advances bloom strikingly in a short-time period. Therefore, we, in this special issue, focus on these new study advances on the south domain of the western CAOB, including the Kazakhstan collage system, Tianshan orogenic belt and Beishan region, and it is anticipated that this issue can draw more attention from the international research groups to be interested in the studies on orogenesis of the CAOB.

    Radon remained a chemical curiosity for decades, promoted at some stage as a health giving gas. Mining related history: (based on ICRP 65) dating back to 15 Century when high mortality from lung cancer was observed among miners in Schneeberg. After the Curies had extracted Radium from Jachymov ores (1898), radon was identified. When measurements were done in Schneeberger and Jachymov mines high concentrations of radon were found. Initially a link was assumed between lung cancer and high radon concentration based on the measurements. (The assumption was not generally accepted).In 1953 William F. Bale indicated that the causative agents of lung cancer was the radon progeny and not radon gas. A possible lung cancer risk to members of the public was discovered very recently (first published results were based on the indoor measurements done in Sweden in a study initiated by Rolf Sievert) Much attention has been given to radon as a radiological health hazard: Recently human exposure to radon progeny in buildings has emerged as an important issue. Lung cancer is the principal concern associated with Rn exposure. The principal concern is associated with radon progeny. These species are chemically reactive, and may be deposited on respiratory tract tissues when inhaled. Subsequent alpha particle decay may damage cells near the deposition site, contributing to increased risk of lung cancer Radon: In Occupational Exposure Protection against Rn Exposure is a Techno-Legal Legal Aspects: There has to be a national legislative framework for the protection of workers against radon The legal framework should entail, inter alia: - Set up of regulator, development of regulations and standards to enable compliance assurance and other protection issues, training of technical people. 10 Legislative Framework in South Africa National Nuclear Regulatory Act (1999) Enables the regulator (NNR) to exercise oversight for Rn protection Occupational Exposure is mainly in Mining and Mineral

    The South Caribbean deformed belt (SCDB) represents a submarine prism formed at the interface between subducting oceanic material in the Colombian and Venezuelan basins and arc terranes along the northern edge of the South American continent. The SCDB and subducted Caribbean slab extends 1500 km from Panama to the Aves Ridge and is similar in scale to better studied magmatic subduction zones in the Lesser Antilles and Central America. The age of subduction of the Venezuelan basin at the SCDB has been examined by dating asymmetrical sediment wedges inferred to have formed above the bending and subducting slab of the Venezuelan basin. Ages are constrained by ties to DSDP wells drilled in the Venezuelan basin ~150 km north of the SCDB. Onlapping wedges are oldest in the western area near the Beata Ridge (middle Eocene), of intermediate age in the central area (early Miocene), and youngest in the east near the Aves Ridge (Mio- Pleistocene). Overlying younger wedges in all areas demonstrate that subduction continued following its initiation. Similar ages of deformed syn-thurst wedges are known from the now inactive continental foreland of northern South America in a belt from western Venezuela to Trinidad. Based on this correlation, we propose a simple back arc thrusting origin for the SCDB that is analogous to the eastern Sunda arc of Indonesia. The obliquity of convergence in the Caribbean case has produced a longlived, eastwardly-migrating backthrust that contrasts to more static backthrust in Sunda. The immediate onset of backthrusting following continental collision means that South America-Caribbean convergence was accommodated by newly organized and focussed subduction at the SCDB backthrust; the "collided" crust of intervening accreted arc terranes remains remarkably unaffected by regional shortening effects.

    2006-01-01

    Full Text Available No study  has been conducted on sexual harassment of physiotherapists in South Africa and it is therefore not known whether harassment occurs and if it does, to what extent. To this purpose, a questionnaire on  sexual harassment and other sexual-related issues in the physiotherapy work environment in South Africa, was sent to a random selection of  982 physiotherapists registered with the Health Professions Council of South Africa. The response rate was 32%. This paper presents the results of the first half of the questionnaire, which was devoted to sexual harassment of the physiotherapist.  Approximately 60% had experienced sexual harassment, of which 83.98% had been perpetrated by patients. Only 5.82% of the respondents had received some form of information in this regard. The most common form of harassment was requests for a hug or kiss.

  5. Economic Freedom and Economic Growth in South Africa

    Directory of Open Access Journals (Sweden)

    Clive E. Coetzee

    2017-06-01

    Full Text Available The economic growth and economic freedom nexus is studied in this article and applied to South Africa in an empirical study. Economic freedom is founded on the free or private market economy, based on competition, where voluntary exchange occurs and a legislative framework ensures the safety of market agents and private property. As part of the literature study, the Index of Economic Freedom, the Economic Freedom of the World Index and the Freedom in the World Index were studied and applied to South Africa. An empirical analysis was conducted, cross-correlation functions were estimated, and Granger causality functions, regression analysis and finally a vector auto-regression model (VAR were constructed and estimated. The research findings from South Africa support the literature, suggesting that there are indeed some indications that greater levels of economic freedom support higher rates of economic growth in a country.

  6. Introduction to South Africa's safety classification

    2012-10-15

    The safety functions of nuclear reactor facilities such as research reactors have to be maintained for all initiating events, incidents and accidents. From the position of licensee, it is a very important issue and design challenge to meet the licensing requirements for the final goal of proper safety functions from nuclear regulator. This paper intends to introduce and understand South Africa's licensing requirements and processing for safety classification of SSCs. South Africa's licensing requirements are shown in Table 1. Three categories A, B and C are categorized based on the occurrence frequency and the dose limitation of worker and public exposure. The Defense in Depth (DiD) and ALARA principle are forced to apply to a nuclear reactor facility design. Also, South Africa's safety and quality class compare with that of ANSI 51.1.

  7. Citizenship in South Africa today. Some insights from Christian ecclesiology

    Directory of Open Access Journals (Sweden)

    Koopman, Nico

    2015-12-01

    Full Text Available This essay reflects upon the notion of citizenship in the context of post-apartheid South Africa. Citizenship discourse in South Africa takes place in the context of the movement away from apartheid, and in the context of the processes of Africanisation and globalisation. An attempt is made to make a contribution to citizenship discourse in South Africa by drawing from theological insights, specifically from the classic formulation of the four marks of the church, namely catholicity, unity, holiness and apostolicity. Based on these ecclesiological marks the following four sets of features of citizenship are identified: apostolic and inclusive citizenship; united and justice-seeking citizenship; holy and virtuous citizenship, and apostolic and responsible citizenship.

    Cancer mortality rates are expected to increase in developing countries. Cancer mortality rates by province remain largely unreported in South Africa. This study described the 2014 age standardised cancer mortality rates by province in South Africa, to provide insight for strategic interventions and advocacy. 2014 deaths data were retrieved from Statistics South Africa. Deaths from cancer were extracted using 10th International Classification of Diseases (ICD) codes for cancer (C00-C97). Adjusted 2013 mid-year population estimates were used as a standard population. All rates were calculated per 100 000 individuals. Nearly 38 000 (8%) of the total deaths in South Africa in 2014 were attributed to cancer. Western Cape Province had the highest age standardised cancer mortality rate in South Africa (118, 95% CI: 115-121 deaths per 100 000 individuals), followed by the Northern Cape (113, 95% CI: 107-119 per 100 000 individuals), with the lowest rate in Limpopo Province (47, 95% CI: 45-49 per 100 000). The age standardised cancer mortality rate for men (71, 95% CI: 70-72 per 100 000 individuals) was similar to women (69, 95% CI: 68-70 per 100 000). Lung cancer was a major driver of cancer death in men (13, 95% CI: 12.6-13.4 per 100 000). In women, cervical cancer was the leading cause of cancer death (13, 95% CI: 12.6-13.4 per 100 000 individuals). There is a need to further investigate the factors related to the differences in cancer mortality by province in South Africa. Raising awareness of risk factors and screening for cancer in the population along with improved access and quality of health care are also important. Copyright © 2017 Elsevier Ltd.

  11. Uranium in South Africa: 1983 assessment of resources and production

    International Nuclear Information System (INIS)

    1984-06-01

    NUCOR assesses South Africa's uranium resource and production capabilities on an ongoing basis. Assessments are carried out in close co-operation with the mining companies and the Government Mining Engineer. In carrying out this evaluation, the classification recommended by the NEA/IAEA Working Party on Uranium Resources is followed. In order to preserve company confidentiality, the details of the findings are released in summary form only. Within South Africa, uranium occurrences are found in Precambrian quartz-pebble conglomerates, Precambrian alkaline complexes, Cambrian to Precambrian granite gneisses, Permo-Triassic sandstones and coal, and Recent to Tertiary surficial formations. South Africa's uranium resources were reassessed during 1983 and the total recoverable resources in the Reasonably Assured and Estimated Additional Resource categories recoverable at less than $130/kg U were estimated to be 460 000 t U. This represents a decrease of 13,4% when compared with the 1981 assessment. South Africa's uranium production for 1983 amounted to 6 060 t U, a 4,21 % increase over the 1982 production of 5 816 t U. Ninety-seven percent of the production is derived from the Witwatersrand quartz-pebble conglomerates, the rest being produced as a by-product of copper mining at Palabora. South Africa maintained its position as a major low-cost uranium producer, holding 14% of the WOCA uranium resources, and during 1982 it produced 14% of WOCA's uranium. In making future production capability projections it may be safely concluded that South Africa would be able to produce uranium at substantial levels well into the next century

  12. Sub-Saharan Africa at the global education market: role of South Africa

    Directory of Open Access Journals (Sweden)

    Ramil Ravilevich Asmyatullin

    2016-12-01

    Full Text Available This article is dedicated to the development of the higher education in Sub-Saharan countries, particularly to the topic of internationalization of education. Most African countries have underdeveloped education systems. The quality and availability of higher education is a formidable obstacle for economic and social development. There is a growing demand for higher education in the SSA, but national education systems can’t cope fully with it. Hence many students go abroad, mostly in other African countries. The article focuses on the position of South Africa in the global and regional education market. As it’s a regional leader in this field South Africa attracts more than a half of international students within the Sub-Saharan Africa. The main reasons why African students choose South Africa are geographic proximity, familiar culture, lack of wanted higher education programs in their countries. However, there are as well disadvantages like xenophobia and race discrimination. South Africa has become a leader in Africa in the field of higher education, but it plays still small part at a global scale.

  13. Psychotherapy in South Africa: the case of Mrs. A.

    Science.gov (United States)

    2007-08-01

    Psychotherapy in South Africa is confronted by issues that reflect the emerging nature of the nascent democracy. Historic racial patterns have characterized the production of psychotherapists and psychologists who are predominantly white female and who often have difficulty mediating the socioeconomic and ethnic reality of their black clientele. Despite this problem, psychotherapists are increasingly relied on and are equipping themselves to intervene meaningfully without their values impacting on the outcomes. These points are illustrated in the case of Mrs. A, who is treated in the cultural context of an evolving South Africa. (c) 2007 Wiley Periodicals, Inc.

    2003-11-01

    Full Text Available While American investors have been able to buy mortgage-backed securities  since the late 1970s and asset-backed securities since the mid-1980s, investors  in South Africa have not become involved in this growing market.  Securitisation also spread to Europe, South America, Asia and Australia during  the 1980s. The first securitisation in South Africa was completed in 1989, but  since then only a few securitised products have been offered to the investment  community. The aim of this article is to investigate the reasons for the lack of  growth in securitisation in South Africa and to determine whether securitisation  will grow to be a significant market in South Africa. The methodology used  includes interviews held with investors, securitisation specialists and other  structured finance specialists from the banking community. Experience from  other countries is noted and included in this article

  20. Psychological capital, a requisite for organisational performance in South Africa

    Directory of Open Access Journals (Sweden)

    Yvonne Du Plessis

    2012-03-01

    Full Text Available Scholars argue that to address the social, economic and political challenges facing South Africa since 1994, organisational managers/leaders should adopt a positive approach, based on sound organisational behaviour. This study administered the Psychological Capital Questionnaire (PCQ to determine whether human resources practitioners (N=131 as custodians of change and positive behaviour in organisations in South Africa embrace core elements of Positive Organisational Behaviour (POB. Exploratory factor analysis resulted in a three-factor model for the PCQ, renamed the Potential South African PsyCap (PSA-PsyCap instrument. All dimensions displayed acceptable reliabilities. Statistically significant differences exist in the POB of demographic groups, relating to age, marital status, home language, seniority and qualifications. This research reveals that South African HR practitioners and managers should fully embrace psychological capital to effectively create caring workplaces taking cognizance of the broader economic and social issues affecting employees and their performance.

  1. Science in South Africa: The dawn of a renaissance?

    Directory of Open Access Journals (Sweden)

    Anastassios Pouris

    2012-07-01

    Full Text Available This article reports the findings of a scientometric analysis of South Africa’s research performance during the period 2000–2010. A multitude of government incentives were introduced during the period and their effects have appeared in the country’s research outputs. In contrast to earlier investigations, it was found that South Africa’s world share of publications is on the verge of reaching the highest contribution ever. South Africa improved its international ranking by two positions during 2000–2010 and was ranked 33rd in the world during 2010. It is argued that, provided the plan of the Minister of Science and Technology to increase the research and development expenditure in the country materialises, South Africa may be on the verge of a scientific renaissance.

  2. Transnational entrepreneurship in the Global South: evidence from Southern Africa

    Directory of Open Access Journals (Sweden)

    Rogerson Jayne M.

    2015-12-01

    Full Text Available Transnational entrepreneurship is an evolving field of research which occupies an interface between social and regional sciences. The phenomenon of transnational entrepreneurship is driven by entrepreneurs that migrate from one country to another whilst maintaining business-related linkages with their former country of origin and the adopted country. The most critical distinguishing feature of transnational entrepreneurs is bifocality or the ability to function across two different business environments. Most writings on transnational entrepreneurship concentrate on business individuals from the global South operating enterprises in the global North. Absent are empirical studies of the nature and behaviour of transnational migrant entrepreneurs who operate across or between emerging or developing economies. This South-South gap in international research concerning transnational entrepreneurship is addressed in the paper which provides an exploratory analysis of the nature of transnational entrepreneurship occurring in Southern Africa using evidence of Zimbabwean transnational entrepreneurs based in Johannesburg, South Africa.

  3. Biohydrogen production as a potential energy fuel in South Africa

    Directory of Open Access Journals (Sweden)

    P.T. Sekoai

    2015-06-01

    Full Text Available Biohydrogen production has captured increasing global attention due to it social, economic and environmental benefits. Over the past few years, energy demands have been growing significantly in South Africa due to rapid economic and population growth. The South African parastatal power supplier i.e. Electricity Supply Commission (ESKOM has been unable to meet the country’s escalating energy needs. As a result, there have been widespread and persistent power cuts throughout the country. This prompts an urgent need for exploration and implementation of clean and sustainable energy fuels like biohydrogen production in order to address this crisis. Therefore, this paper discusses the current global energy challenges in relation to South Africa’s problems. It then examines the feasibility of using biohydrogen production as a potential energy fuel in South Africa. Finally, it reviews the hydrogen-infrastructure development plans in the country.

  4. Status of marine pollution research in South Africa (1960-present).

    Science.gov (United States)

    Wepener, V; Degger, N

    2012-07-01

    The published literature on marine pollution monitoring research in South Africa from 1960 to present was evaluated. There has been a general decline in the number of papers from the 1980s and this can be linked to the absence of a marine pollution monitoring programme in South Africa. General trends observed were that contaminant exposure monitoring of metals predominates the research conducted to date. Monitoring results indicate that there has been a general decrease in metal concentrations in South African coastal waters and concentrations of metals and most organics in mussels are lower than in other industrialised nations. This is reflected in the general pristine nature and high biodiversity of the South African coastline. The establishment of a national marine pollution monitoring framework would stimulate marine pollution research. Copyright © 2012 Elsevier Ltd. All rights reserved.

  7. Africa's middle class women bring entrepreneurial opportunities in breast care medical tourism to South Africa.

    Science.gov (United States)

    Ahwireng-Obeng, Frederick; van Loggerenberg, Charl

    2011-01-01

    Africa's distribution of specialized private health services is severely disproportionate. Mismatch between South Africa's excess supply and a huge demand potential in an under-serviced continent represents an entrepreneurial opportunity to attract patients to South Africa for treatment and recuperative holidays. However, effective demand for intra-African medical tourism could be constrained by sub-Saharan poverty. Results from interviewing 320 patients and five staff at the Johannesburg Breast care Centre of Excellence, however, reject this proposition, Africa's middle class women being the target market estimated to grow annually by one million while breast cancer incidence increases with middle-class lifestyles. Uncovering this potential involves an extensive marketing strategy. Copyright © 2010 John Wiley & Sons, Ltd.

  10. Spaces of alienation: Dispossession and justice in South Africa

    Directory of Open Access Journals (Sweden)

    Petrus T. Delport

    2016-12-01

    Full Text Available Theories and philosophies of space and place have seen a rise in prominence in recent times, specifically in the disciplines of theology, law and philosophy. This so-called spatial turn in contemporary theory is one that attempts to think through the vicissitudes and conceptual lineages related to the existence of space as both a physical and a social reality. The politics of space in South Africa, however, cannot be thought of separately from the concept of alienation. South Africa is a space whose existence is predicated upon a relationship of alienation to its located place. South Africa, like most other settler colonies, is a space that was created through occupation and alienation: the occupation of a territory and the alienation of the indigenous people from this occupied territory. This relationship of alienation is not only observable in the physical reality engendered by this occupied space but also by its social reality. In this paper we reflect on the intersections of the physical and social manifestations – in Bourdieu’s sense – of an occupied space and consider its effects of alienation on the indigenous people. To this end we will proceed to interrogate current South African geographical markers – such as the existence of townships and suburbs – from its positionality within the history of South Africa as an occupied space. To discern a theological agenda for the issue of spatial justice would also require an investigation into the theological agenda that prohibited the realisation of spatial justice in South Africa or, in other words, the religious reconciliation preached post-1994 at the expense of justice.
